The Delft University of Technology (TU Delft; Dutch: Technische Universiteit Delft) is the oldest and largest Dutch public technical university, located in Delft, The Netherlands. It specializes in engineering, technology, computing, design, and natural sciences.

With eight faculties and multiple research institutes, TU Delft educates more than 26,000 students (undergraduate and postgraduate), and employs more than 3,000 doctoral candidates and 4,000 teaching, research, support and management staff (including more than 1,300 faculty members of all ranks).

The university was established on 8 January 1842 by King William II as a royal academy, with the primary purpose of training civil servants for work in the Dutch East Indies. The school expanded its research and education curriculum over time, becoming a polytechnic school in 1864 and an institute of technology (making it a full-fledged university) in 1905. It changed its name to Delft University of Technology in 1986.

Dutch Nobel laureates Jacobus Henricus van 't Hoff, Heike Kamerlingh Onnes, and Simon van der Meer have been associated with TU Delft. TU Delft is a member of several university federations, including the IDEA League, CESAER, UNITECH International, ENHANCE Alliance, LDE, and 4TU.

Delft University of Technology was founded on 8 January 1842 by William II of the Netherlands as Royal Academy for the education of civilian engineers, for serving both nation and industry, and of apprentices for trade. One of the purposes of the academy was to educate civil servants for the colonies of the Dutch East India Company. The first director of the academy was Antoine Lipkens, constructor of the first Dutch optical telegraph, called simply as Lipkens. Royal Academy had its first building located at Oude Delft 95 in Delft. On 23 May 1863 an Act was passed imposing regulations on technical education in the Netherlands, bringing it under the rules of secondary education.

On 20 June 1864, Royal Academy in Delft was disbanded by a Royal Decree, giving a way to a Polytechnic School of Delft (Politechnische School te Delft). The newly formed school educated engineers of various fields and architects, much needed during the rapid industrialization period in the 19th century.

Yet another Act, passed on 22 May 1905, changed the name of the school to Technical College (Institute) of Delft (Technische Hoogeschool Delft, from 1934 Technische Hogeschool Delft), emphasizing the academic quality of the education. Polytechnic was granted university rights and was allowed to award academic degrees. The number of students reached 450 around that time. The official opening of the new school was attended by Queen Wilhelmina on 10 July 1905. First dean of the newly established college was ir. J. Kraus, hydraulic engineer. In 1905, the first doctoral degree was awarded. From 1924 until the construction of the new campus in 1966, the ceremonies were held in the Saint Hippolytus Chapel.

Corporate rights were granted to the college on 7 June 1956. Most of the university buildings during that time were located within Delft city centre, with some of the buildings set on the side of the river Schie, in the Wippolder district.

Student organizations grew together with the university. The first to be established on 22 March 1848 is the Delftsch Studenten Corps housed in the distinctive Sociëteit Phoenix on the Phoenixstraat. This was followed by the Delftsche Studenten Bond (est. 30 October 1897) and the KSV Sanctus Virgilius (est. 2 March 1898). In 1917, Proof Garden for Technical Plantation (Dutch: Cultuurtuin voor Technische Gewassen) was established by Gerrit van Iterson, which today is known as Botanical Garden of TU Delft. In that period, a first female professor, Toos Korvezee, was appointed.

After the end of World War II, TU Delft increased its rapid academic expansion. Studium Generale was established at all universities in the Netherlands, including TU Delft, to promote a free and accessible knowledge related to culture, technology, society and science. Because of the increasing number of students, in 1974 the first Reception Week for First Year Students (Ontvangst Week voor Eerstejaars Studenten, OWEE) was established, which has become a TU Delft tradition since then.

Since 2006 all buildings of the university are located outside of the historical city center of Delft. The relatively new building of Material Sciences department was sold, later demolished in 2007 to give place for a newly built building of the Haagse Hogeschool. Closer cooperation between TU Delft and Dutch universities of applied sciences resulted in physical transition of some of the institutes from outside to Delft. In September 2009 many institutes of applied sciences from the Hague region as well as Institute of Applied Sciences in Rijswijk, transferred to Delft, close to the location of the university, at the square between Rotterdamseweg and Leeghwaterstraat.

In 2007 the three Dutch technical universities, TU Delft, TU Eindhoven and University of Twente, established a federation, called 3TU.

On 13 May 2008, the building of the Faculty of Architecture was destroyed by fire, presumed caused by a short circuit in a coffee machine due to a ruptured water pipe. Luckily, the architecture library, containing several thousands of books and maps, as well as many architecture models, including chairs by Gerrit Rietveld and Le Corbusier, were saved. The Faculty of Architecture is currently housed in the university's former main building.

Through the course of the years the logo of the TU Delft changed a number of times, along with its official name. The current logo is based on the three university colors cyan, black and white. The letter "T" bears a stylized flame on top, referring to the flame that Prometheus brought from Mount Olympus to the people, against the will of Zeus. Because of this, Prometheus is sometimes considered as the first engineer, and is an important symbol for the university. His statue stood in the center of the newly renovated TU Delft campus, Mekelpark, until it was stolen in 2012.

Initially, all of the university buildings were located in the historic city centre of Delft. This changed in the second half of the 20th century with relocations to a separate university neighbourhood. The last university building in the historic centre of Delft was the university library, which was relocated to a new building in 1997. On 12 September 2006, the design of the new university neighbourhood, Mekelpark, was officially approved, giving a green light to the transformation of the area around the Mekelweg (the main road on the university terrain) into a new campus heart. The new park replaced the main access road and redirected car traffic around the campus, making the newly created park a safer place for bicycles and pedestrians.

A new university neighborhood called Mekelpark (its name commemorating TH Delft professor and WW II resistance fighter, Jan Mekel, who was executed by the Nazis on 2 May 1942 in Sachsenhausen) was opened on 5 July 2009. Mekelpark replaced old parking structures, bike lanes and filling stations, constructed between faculty buildings of the university in the late 1950s. Its 832-meter-long promenade eased the commute between faculty buildings. Both sides of the promenade are covered by stone benches, 1547 meters long in total. Some of the university buildings around the Mekelpark deserve certain attention.

TU Delft Aula was designed by Van den Broek en Bakema architecture bureau, founded by two TU Delft alumni Jo van den Broek and Jaap Bakema. It was officially opened on 6 January 1966 by Dutch Prime Minister Jo Cals. It is a classical example of a structure built in Brutalist style. TU Delft Aula, which symbolically opens the Mekelpark, houses main university restaurant and store, as well as lecture halls, auditoria, congress center, and administrative offices of the university. All doctoral promotion, honoris causa ceremonies, as well as academic senate meetings take place in the Aula.

The TU Delft Library, constructed in 1997, was designed by Delft-based Mecanoo architecture bureau. It is located behind university aula. The roof of the library is covered with grass, which serves as a natural insulation. The structure lifts from the ground on one side allowing to walk to the top of the building. The library is topped by the steel cone, giving its unique shape. All the walls are completely filled with glass. The library won the Dutch National Steel Prize in 1998 in the buildings of steel and hybrid constructions category. The library is also host of the 4TU.Centre for Research Data, the archive for research data in the technical sciences in the Netherlands.

The TU Delft Sports and Culture Center, recently renamed X, is located at Mekelweg 10, at the edge of the Mekelpark. It was designed by architect Vera Yanovshtchinsky and opened to TU Delft students and staff in 1995. Since then it has undergone expansions and renovations.

Three musea are associated with the university: Science Centre Delft, Mineralogy-geology museum and Beijerinck en Kluyver archive.

Science Centre Delft was opened in September 2010 and is located at Mijnbouwstraat 120 in Delft. Science Center Delft is a successor of Technical Exhibition Center. Technical Exhibition Center was established by a group of TU Delft professors with the aim of presenting the recent advances in technology to a wider audience. Parts of the collection were shown outside of Delft: in the Netherlands and abroad, including Israel and Czech Republic. The collection was permanently hosted in the building of former department of geodesy. The historical collections of Technical Exhibition Center were moved Delft Museum of Technology, located at Ezelsveldlaan, in the buildings of the former department of naval architecture (Werktuig- en Scheepsbouwkunde), next to the city center of Delft. As Delft city council together with TU Delft decided to move the collection close to the university campus (currently the building of the former museum are transformed into lofts), Science Centre Delft shows visitors current TU Delft research projects are available, including Eco Runner and Nuna.

Beijerinck en Kluyver archive hosts a collection of documents, exhibits and memorabilia of two scientists historically connected with the university.

Mineralogy-geology museum is a part of TU Delft Faculty of Civil Engineering and Geosciences and contains around 200,000 geological, mineralogical and crystallographical items divided into numerous sub-collections. The oldest items date back to 1842 when the TU Delft (then Delft Royal Academy) was established.

TU Delft botanical garden dates back to 1917, where Proof Garden for Technical Plantation (Dutch: Cultuurtuin voor Technische Gewassen) was established by Gerrit van Iterson Jr., TU Delft graduate and assistant to Martinus Beijerinck. Gerrit van Iterson Jr. was the first director of the garden until 1948. Creation of botanical gardens at TU Delft was partially a result of the increasing needs of systematized development of tropical agriculture in then Dutch colony of Dutch East Indies. Over 7000 different species of plants, including tropical and subtropical plants, herbs, and ornamental plants cover the area of almost 2.5 ha. Furthermore, more than 2000 unique species are preserved in university's greenhouses. All facilities of TU Delft botanical garden are open to the public.

Building 28 is the main building of Computer Science on campus. It hosts research groups of Intelligent Systems and Software Technology departments, educational and research labs, student study areas, meeting rooms, and the support staff of Computer Science.

Along with Delft, UNStudio developed the 'Echo' building on the TU campus for interfaculty lecture halls and project rooms, student study areas, Computer Science (Cybersecurity section and Sequential Decision Making section) research offices, and meeting rooms. It is an energy-producing building within the campus of Delft which aims at energy conservation to delve into the future. Echo won the prestigious World Prix Versailles (Campuses category) in 2023.

In September 2016, TU Delft inaugurated a new campus in The Hague. The MSc programme Engineering and Policy Analysis (EPA), which teaches students to operate at the intersection of technology and policy when tackling wicked problems, was relocated to this new site to capitalize on its proximity to government ministries, international bodies, and multinational organizations.

TU Delft operates the 5th floor of the Wijnhaven Building at Turfmarkt 99 in The Hague, with the rest of the building being occupied by Leiden University. Originally the Ministry of the Interior's headquarters at Schedeldoekshaven 200, the Wijnhaven Building, named after the historic Wijnhavenkwartier, was converted into Campus The Hague in 2016.

In 2023, TU Delft announced plans to further expand its footprint in The Hague by launching a joint university facility with Leiden University at Spui, set to open in 2025. This new location is expected to accommodate around 600 TU Delft students in the city centre of The Hague.

Since 2004, the TU Delft education system is divided into three tiers: the bachelor's degree, master's degree, and doctorate. The academic year is divided into two semesters: the first semester from September until January and the second semester from the end of January until July. Most of the lectures are available through OpenCourseWare.

As of 2016, TU Delft offers 16 BSc programmes. TU Delft students obtain their degree after a three-year study. The test project finalizes the BSc studies. All BSc programmes are taught in Dutch, except for Aerospace Engineering, Applied Earth Sciences, Nanobiology, and Computer Science, which are taught entirely in English, and Electrical Engineering which is taught in a mixture of both.

TU Delft offers around 40 MSc programmes. The MSc studies take two years to complete.

TU Delft uses the European Credit Transfer System, where each year MSc students are required to obtain 60 ECTS points. An honours track exists for motivated MSc students, who obtained a mark of 7.5 or higher (in Dutch grading scale) and did not fail any courses. This track, associated with 30 ECTS points, is taken alongside the regular MSc programme and must be related to student's regular degree courses or the role of technology in society. The honours track must be completed within the time allowed for the MSc programme.

MSc programmes are also offered through the 3TU federation, Erasmus Mundus programmes, IDEA League joint MSc programs and QuTech Academy.

Doctoral studies at TU Delft are divided into two phases. The first phase, lasting one year, serves as a trial period during which the doctoral candidate must prove capability for performing research on a doctoral level. The candidate must pass the evaluation performed at the end of the year by his/her promoter in order to continue doing research the following three years. The research the candidate performs must be finalized by submitting a doctoral thesis. The thesis is evaluated by a doctoral committee composed of TU Delft professors and external opponents. Once the thesis has been revised and comments have been taken into account, the candidate gives a formal doctoral defense.

In contrast to US graduate school, other duties such as following lectures and giving TAs form only a small portion of the programme.

The doctoral defense is of ceremonial nature and is held in the senate room. It lasts exactly one hour, during which the doctoral candidate must answer all questions from the committee. Sometimes the candidate is accompanied by one or two paranymphs, who theoretically might help defend a question asked by a committee member. The defense is ended by the pedel, who enters the room and says in Latin Hora est (It is time), stamping the university staff on the floor. The committee then moves to a separate room to decide whether to grant the candidate a doctorate or not. Then the committee returns to the room where the defense was held, and if the doctorate is granted the promoter presents the laudation praising the new doctor. The entire ceremony is chaired by the rector or a representative.

TU Delft also offers Professional Doctorate in Engineering.

TU Delft has three officially recognized research institutes: Research Institute for the Built Environment, International Research Centre for Telecommunications-transmission and Radar, and Reactor Institute Delft. In addition to those three institutes, TU Delft hosts numerous smaller research institutes, including the Delft Institute of Microelectronics and Submicron Technology, Kavli Institute of Nanoscience, Materials innovation institute, Astrodynamics and Space Missions, Delft University Wind Energy Research Institute, TU Delft Safety and Security Institute, and the Delft Space Institute, Delft Institute of Applied Mathematics is also an important research institute which connects all engineering departments with respect to research and academia. A complete list of research schools is available on TU Delft website.

Important part of Dutch university system are research schools. They combine education, training and research for PhD candidates and postdoctoral researchers in a given field. The main goal of the research schools is to coordinate nationwide research programs in a given area. Research schools of TU Delft cooperate with other universities in the Netherlands. Research schools are required to have an accreditation of Royal Netherlands Academy of Arts and Sciences. TU Delft is taking the lead in ten research schools, and participates in nine. The full list of research schools affiliated with TU Delft is available on TU Delft website, see for example TRAIL Research School.

During an academic year the TU Delft publishes a weekly magazine: Delta, which aims at the student and employee community of the university. The newspaper is predominantly in Dutch, with the last few pages published in English. TU Delta is distributed freely in paper form over the campus and is also available for free on the Internet. Articles focus mainly on current university affairs and student life. The weekly agenda including PhD promotions, inaugural lectures, etc. is also published therein.

Also, approximately four times a year, the TU Delft publishes a magazine devoted only to research conducted by the university, called Delft Outlook. Delft Outlook is published in English, while the same content is published in Dutch in Delft Integraal magazine. Both magazines present interviews with TU Delft researchers, university officials. Columns by some university professors are published therein, as well as alumni letters and excerpts from recently published PhD theses.

TU Delft is governed by the executive board (College van Bestuur), controlled and advised by student council, workers council, board of professors, board of doctorates, assistant staff office, committee for the application of the allocation model, operational committee, advisory council for quality and accreditation, deans of each TU Delft faculty, and directors of TU Delft research centers, research schools and research institutes.

Executive board is chaired academically by the Rector Magnificus. The currently appointed Rector Magnificus, Tim van der Hagen, has held the position since 2018. He replaced Prof. Ir. Karel Ch.A.M. Luyben who was rector for the period 2010 to 2018. Previous Rectors of TU Delft include Prof. K.F. Wakker (1993–1997 and 1998–2002), Prof. J. Blauwendraad (1997–1998) and Prof. J.T. Fokkema (2002–2010). Executive board is accountable to the Supervisory Board, appointed by the Minister of Education, Culture and Science. One of the many tasks of executive board is the approval of management regulations.

Board of professors advises in the matter of academic quality, deciding on the selection of guest lecturers, research fellows as well as revising proposals submitted for royal honors for professors. Board of doctorates appoints supervisors for PhD students, forms promotion committees, determines promotional code, and confers PhD and doctorate Honoris Causa degrees. Committee for the application of the allocation model reports to the executive board regarding allocation model. Further, it controls output data supplied to the executive board. Operational committee is composed of members of the executive board and the s. The committee collaborates on the issues of general importance, related in part to the specific interests of the faculties, and strengthens the unity of the university overall.

Student life at TU Delft is organized around numerous student societies and corporations. They can be generally categorized into professional societies, social societies and sport societies. More than half of TU Delft students belong to an officially recognized society.

There are two student parties at TU Delft: ORAS (Organisatie Rationele Studenten) and Lijst Bèta (successor of AAG). AAG (Afdeling Actie Groepen) started as an action group of students in the 1960s, willing to have more impact on the quality of education at the then Polytechnic Institute Delft. ORAS became active in the early 1970s as a counterbalance to AAG. After already taking a break from the yearly elections in 2008, AAG did not participate anymore in the elections of 2010 due to disappointing results. In 2011, a new party was established, Lijst Bèta, that got 2 out of the 10 seats in the student counsil. Since then, Lijst Bèta and ORAS compete each year for seats in TU Delft's Students Council (Studenten Raad). Further, all student organizations of TU Delft are associated with The Council of Student Societies Delft VeRa (De VerenigingsRaad) and The Society for Study and Student Matters Delft VSSD (Vereniging voor Studie- en Studentenbelangen Delft).

Apart from bachelor and master student organizations, PhD students of TU Delft have their own organization called Promood (PhD Students Discussion Group Delft) (Promovendi Overleg Delft), which represents TU Delft PhD students at the university. It is also a member of Dutch PhD Students Network (Promovendi Netwerk Nederland).

Each faculty of TU Delft has its own set of professional student organizations. Numerous societies are present at the university, many of them with rich traditions, customs and history. For example, aerospace engineering department hosts Foundation for Students in Airplane Development, Manufacturing and Management (Stichting Studenten Vliegtuigontwikkeling, -bouw en -beheer), while civil engineering department Society for Practical Studies. International professional student organizations are also present at TU Delft, including European Association of Aerospace Students.

Apart from professional student societies, students organize themselves only for the purpose of enriching their social life. Many of the societies have sectarian roots, like a Catholic Wolbodo Student Society, Katholieke Studentenvereniging Sanctus Virgilius Delft, that during the course of the years lost the religious affiliations and accepts students from any denomination. Besides societies which have their roots in religion, there are also general (with no religious bonds) societies. One of these is Sint Jansbrug. These societies accept anyone who studies at the TU Delft or any other higher education facility in the Delft area. Also organization that has its roots in Rover Scout movement Delftsche Zwervers (at the same time the oldest student scouting group in the world) is present or local branch of the European AEGEE.

Student sports are organized around clubs, that focus mostly on single discipline. Those include rowing society D.S.R.V. Laga and rowing club Proteus-Eretes (both with many Olympic medals won by the members of the club) or American football club Delft Dragons.

TU Delft researchers developed many new technologies used today, including GLARE, a fibre metal laminate used in Airbus A380 skin and Vision in Product Design design method. Cees Dekker's lab at TU Delft demonstrated in 1998 the first transistor made out of single nanotube molecule. The Delta Works plan was, in part, a child of TU Delft graduates, including Johan Ringers and Victor de Blocq van Kuffeler. TU Delft was a precursor of the Open design concept.

In architecture, TU Delft is famous for Traditionalist School in Dutch architecture. TU Delft was a home to many prominent microbiologists including Martinus Beijerinck, who in 1898 discovered viruses while working at TU Delft, and Albert Kluyver, father of comparative microbiology, which resulted in the creation of so-called Delft School of Microbiology.

The majority of TU Delft's students are male. In 2021, among all students of the university (MSc and BSc level) 30% were women. The biggest imbalance between men and women is seen in the Mechanical engineering faculty, while the smallest is seen at Industrial Design and Architecture departments. Despite many efforts of the university to change that imbalance, the number of women studying at TU Delft has stayed relatively constant over the years.
