Widener University is a private, metropolitan university with a Chester, Pennsylvania, campus that includes six colleges and schools, and two distinct law schools in Harrisburg, Pennsylvania, and Wilmington, Delaware.

The university offers associate’s, bachelor’s, master's, and doctoral degrees in a variety of fields across liberal arts, business, and engineering, to nursing and a variety of health and human service professional programs. It is classified among "Doctoral/Professional Universities" and a "Community Engagement Institution".

Founded as the Bullock School for Boys in 1821, the school was established in Wilmington, Delaware. It became the Alsop School for Boys from 1846 to 1853, and then Hyatt's Select School for Boys from 1853 to 1859. Military instruction was introduced in 1858, and the school changed its name in 1859 to Delaware Military Academy. It moved to Pennsylvania in 1862 and became Chester County Military Academy. It was known as Pennsylvania Military College after 1892 and adopted the Widener name in 1972.

Widener University was founded in 1821 as the Bullock School for Boys preparatory school in Wilmington, Delaware, by John Bullock. Bullock operated the school until 1846 when it was sold to Samuel Alsop and renamed the Alsop School for Boys. In 1853, the school was sold to Theodore Hyatt and renamed the Hyatt's Select School for Boys, and again in 1859 to the Delaware Military Academy.

In 1862, the school moved to West Chester, Pennsylvania. By act of assembly on April 8, 1862, the Pennsylvania legislature incorporated the school as a university under the name of Chester County Military Academy.

In 1865, the school moved to Chester, Pennsylvania, and occupied the building which would become the Old Main building of the Crozer Theological Seminary. By 1868, the school outgrew the Crozer Old Main building and relocated to its current location.

From 1892 to 1966, the school was known as Pennsylvania Military College (PMC) and was under the direction of General Charles Hyatt. PMC was once one of the nation's senior military colleges. In 1869, Pennsylvania Military College was the first school to have a U.S. Army detail stationed at the school and to receive federal arms for training. In 1904, the school was recognized on the first list of distinguished institutions published by the U.S. War Department. In 1923, "American March King" John Philip Sousa wrote and dedicated "The Dauntless Battalion" march to PMC's President (Colonel Charles E. Hyatt), the faculty and the cadets of PMC. Sousa had been presented with an honorary doctor of music degree by the college in 1920, and he was impressed by the cadet cavalry horsemen.

In 1966, the school changed its name again to PMC Colleges, which incorporated Pennsylvania Military College as well as Penn Morton College, which had a non-military, co-educational curriculum. The school expanded the Chester campus from 25 acres to 90 acres. Graduate programs were introduced in 1966, and female students were first enrolled in 1967.

In 1972, the institution was renamed Widener College to honor the memory of Eleanor Elkins Widener, the maternal grandmother of Fitz Eugene Dixon Jr., a generous supporter of the organization over four decades and a member of the prominent Widener family of Philadelphia. The Corps of Cadets disbanded, although an Army ROTC program was retained. The Widener University School of Law was acquired in 1975, which was split in 2015 to become two separate law schools: one on the Delaware campus and another in Harrisburg – Widener University Commonwealth Law School. In recognition of its comprehensive offerings, Widener College became Widener University in 1979. Today, Widener is a four-campus university offering more than 80 programs of study.

The Manor House was designed and built by Jonathan Edwards Woodbridge in 1888 at 14th and Potter Street. It was a wedding gift to his wife, Louise Deshong, and was originally named "The Louise". It was modeled after the late 19th-century English country manor style and is unique for its hand-made brick construction.

The house was given to the city of Chester as a home for young women. In 1976, Widener University purchased the home for use as a student residence. It later became home to the Phi Sigma Sigma sorority. The home is currently used by Widener University as a student dormitory.

The Old Main and Chemistry Building were listed on the National Register of Historic Places in 1978.

Throughout its long history, the university has undergone several name changes. The following table details the various names Widener has held over the years as well as any significant organizational changes that occurred during each period.

Widener School of Law opened in 1976. In July 2015, Widener School of Law, which used to be one school sitting on the Delaware and Harrisburg campuses, split to become Widener University Delaware Law School in Wilmington and Widener University Commonwealth Law School in Harrisburg.

Widener's academic offerings include over 50 undergraduate majors, 40 minors, and more than 30 graduate programs of study.

In 1979, Widener University leased and restored the Deshong Art Museum located on Edgemont Avenue in Chester. The Deshong Art Museum was built in 1914 after the death of the art collector and wealthy industrialist Alfred O. Deshong left his trust and land to the city of Chester. Deshong donated over 300 pieces of art to the museum including carved Japanese ivory figures, Chinese carved hard stone vessels and 19th century American and European paintings.

Over the years, the museum fell into disrepair and in July 1984 the trustees that managed the art museum dissolved the trust. The Asian and impressionistic art collection were given to Widener University and are displayed in their permanent collection.

The PMC Museum highlights the legacy of the Pennsylvania Military Academy of Cadets with exhibits of sabres, uniforms, scrapbooks, newspapers, and yearbooks.

In 2013, Widener was named a finalist for the President's Higher Education Community Service Honor Roll Presidential award – one of only 14 institutions in the nation to receive that honor.

• University Technology Park — A joint project started in 1999 between the university and Crozer-Keystone Health System to foster small business opportunities focusing on health care, science and technology. It currently consists of two buildings (with three more planned) on 20 acres (81,000 m) and is located directly in between the Main Campus and Crozer-Keystone Medical Center.
• Widener University Observatory — The observatory has free public telescope viewings throughout the school year hosted by the physics and astronomy department.

In 2006, the university established a new charter school near the Chester campus to serve local residents from kindergarten to grade 5. Named the Widener Partnership Charter School, the school utilizes the university's programs in education, social work, nursing, and clinical psychology. This collaboration involves the participation of Widener faculty and students to not only provide educational support but also provide additional assistance outside of school through counseling and health services.

Classes in the charter school started in September 2006, enrolling 50 students in both kindergarten and grade 1. The school continued to add a new grade each year until grade 8 had been reached, surpassing the initial expectations of the project.

A $50 million revitalization project was started in 2007. The project, named University Crossings, included the addition of a hotel, bookstore, coffee shop, restaurant, and apartments. The project is expected to have an overall economic impact of $1 million to Chester, as well as creating 100 new jobs.

In 2017, Widener University purchased the Taylor Memorial Arboretum in Nether Providence Township about 1 mile north of the Chester campus. The university purchased the site from BNY Mellon bank and plans to use the nature reserve for research and hands-on learning opportunities for citizen science projects.

As of 2011, there were 59,018 total living alumni.
