California State Polytechnic University, Humboldt (Cal Poly Humboldt or Humboldt) is a public university in Arcata, California. It is one of three polytechnic universities in the California State University (CSU) system and the northernmost campus in the system.

The main campus, situated hillside at the edge of a coast redwood forest, overlooks Arcata, much of Humboldt Bay, and the Pacific Ocean. The college town setting on the California North Coast, 8 miles (13 km) north of Eureka, 279 miles (449 km) north of San Francisco, and 654 miles (1053 km) north of Los Angeles is notable for its natural beauty. It is the most westerly four-year university in the contiguous United States. Humboldt is a Hispanic-serving institution (HSI).

The university is divided into three colleges: the College of Arts, Humanities, and Social Sciences; the College of Natural Resources and Sciences; and the College of Professional Studies. It offers 58 bachelor's degree programs, 14 master's degree programs, 76 minors, and 4 credential programs. Cal Poly Humboldt does not offer doctoral degrees.

Humboldt State Normal School was established as a teacher's college on June 16, 1913, by California governor Hiram Johnson. It was one of about 180 "normal schools" founded by state governments to train teachers for the rapidly growing public common schools. Some closed but most steadily expanded their role and became state colleges in the early 20th century and state universities in the late 20th century. The cities of Arcata and Eureka (and to a lesser extent Fortuna) competed with one another to host the new campus. Arcata eventually won the university when William Preston, and the Union Water company, donated 55-acres. It opened on April 6, 1914, in the former Arcata Grammar School building with 78 students and 5 faculty. On May 26, 1915, the first commencement of the first graduating class occurred, a class of 15 women.

The school was put under the jurisdiction of the California Department of Education, renamed Humboldt State Teacher's College and Junior College, and moved to its current location in 1921. In 1924, during the presidency of Ralph Waldo Swetman, the Associated Students and the Alumni Association were organized and The Foghorn, the first student newspaper, was published. Bachelor's degrees began being offered in 1927. The school was renamed Humboldt State College in 1935 and the next year the Lumberjack was adopted as its mascot. In 1937, the students opened a cooperative bookstore and soda fountain, which would exist for the next 40 years as the center of student life.

During World War II, Arcata's city defense council suggested camouflaging Founder's Hall, which is visible from the Pacific Ocean, so it would not be a target for Japanese submarines. The council made its request in 1942, but Founder's Hall was not painted until the spring of 1944. The building remained camouflage green until 1948. During WWII, President Arthur Gist corresponded back and forth with the hundreds of students who left Humboldt State College to serve in the war. Available for viewing in the Arthur Gist Letters at HSU Special Collections, there are over 1,000 letters from 365 servicemen and women writing to Gist for the duration of the war.

Graduate programs were first offered in 1947. Under President Cornelius H. Siemens in 1952, HSU continued expanding by accepting students from abroad, including some from Yugoslavia, Germany, the Near East as well as US territories such as American Samoa, Guam and Hawaii. KHSC, later KHSU, the first state college radio station in California, was established. In 1960, the college joined the newly formed California State College system. The junior college program, terminated at HSU in 1962, was re-established in 1964 at College of the Redwoods (CR) located at the southern edge of Eureka. CR is located only seventeen miles south of HSU, and the two institutions maintain a close working relationship, with many students transferring to HSU following graduation from CR.

Student activism on campus rose through the 1960s and early 1970s, peaking in a protest against the Vietnam War with about 800 students (out of 3,600) participating in demonstrations on October 15, 1969. This was followed by another protest with nearly 3,000 students who planned a strike after the Cambodian Incursion. With similar events across the state, Governor Ronald Reagan shut down the CSC system in May 1970 for five days. The 1970s also saw the rise of feminist, cultural, and LGBT groups, and though the Women's Center was the only one to survive through the 1980s, most groups reappeared by the mid-1990s.

Alumnus David Philips established the Humboldt Film Festival in 1967. It is now one of the oldest student-run festivals in the world. In 1996 the annual Explorations in Afro-Cuban Dance and Drum workshop began being held on the campus every July. The workshop is the largest assemblage of Afro-Cuban folkloric masters in the United States, drawing students from across the country and around the world.

In 1972, the college was renamed California State University, Humboldt. However, it still continued to be popularly called "Humboldt State." Reflecting this, its name was simplified to Humboldt State University in 1974. Enrollment first reached 7,500 in 1974, and the university remains one of the smallest in the CSU system. Through the 1980s, mature students became a large part of Humboldt State's student body, and in 1986 40% of the students were over the age of 25. The number has since decreased to 30%.

In 1987 students and activists founded the optional Graduation Pledge of Social and Environmental Responsibility. The purpose of the Pledge is to encourage graduating students to be mindful of the social and environmental impacts of their employment as they enter the workforce or continue their education. Today over one hundred Universities and colleges worldwide use the Pledge to some extent.

On April 22, 2024, dozens of pro-Palestinian protesters occupied Siemens Hall as part of a wider movement of occupation protests against the Israel–Hamas war. Protesters renamed the building to "Intifada Hall" and managed to repel an initial police incursion. At some point protesters occupied a second building, Nelson Hall. On April 30, a large law enforcement task force stormed both occupied buildings and arrested at least 35 people, bringing the occupation to an end.

The university, founded as Humboldt State Normal College in 1913, took the name of the county and nearby bay, which was originally named after the famous German scientist Alexander von Humboldt.

On May 23, 1972, fourteen of the nineteen CSU campuses were renamed to "California State University," followed by a comma and then their geographic designation. The five campuses exempted from renaming were the five newest state colleges created during the 1960s. The new names were very unpopular at certain campuses. Over the objections of CSU Chancellor Glenn S. Dumke, state Assemblyman Alfred E. Alquist proposed a bill that would rename the San Jose campus back to San Jose State. A few years later, some other CSU campuses, alongside the Humboldt campus, also secured passage of similar legislation, and California State University, Humboldt was renamed Humboldt State University from 1974 until 2022.

On January 26, 2022, the university was officially renamed from Humboldt State University to California State Polytechnic University, Humboldt, becoming the third polytechnic university in the state. The change is backed by a $458 million investment from the state of California.

The university is divided into three colleges: the College of Arts, Humanities, and Social Sciences; the College of Natural Resources and Sciences; and the College of Professional Studies. There are 48 undergraduate majors and 69 minors. The two largest majors are biology and art, both with over 20 faculty members and extensive facilities on- and off-campus. This CSU campus offers a wildlife undergraduate degree. There are several credential programs and fourteen master's programs, of which natural resources and social work are the largest. The new Energy, Environment, and Society graduate program is unique to the CSU, and provides graduates with interdisciplinary training in engineering, economics, and climate policy.

The University Library supports students and faculty from all three academic colleges. Humboldt State University Press (now called the Press at Cal Poly Humboldt) was launched in 1991 to showcase research and scholarship across the campus. The Forestry department building's walls are completely paneled with different species of wood. The building was rebuilt in October 1980 after the original building was burned down. The original building stood for 17 years before an arsonist, whose identity is still unknown today, set the building on fire in 1979.

Cal Poly Humboldt is one of only two universities in California to offer a major in botany; the other is California State Polytechnic University, Pomona. Its botany program is the nation's largest undergraduate program. Cal Poly Humboldt is the only university in California to offer a degree in rangeland resources and wildland soil science. The Native American Studies major and the Oceanography major are also unique to the California State University system. The university offers unique minors including multicultural queer studies, scientific diving, and appropriate technology.

The university's location on the North Coast provides access to the Pacific Ocean, lagoons, marshes, estuaries, and the Fred Telonicher Marine Laboratory, which provides opportunities for "hands-on" experiences and research for the sciences. The Marine Lab was opened in 1966, the lab is open during the academic school year (mid August-mid May).

Cal Poly Humboldt's fire science program teaches modern techniques for managing wildfire, and an advanced training program is offered for Forest Service employees and similar professionals.

The International English Language Institute has worked alongside HSU for 22 years to help international students gain academic English language skills to further their academic pursuits and business careers.

The college of eLearning & Extended Ed (CEEE) is a self-supporting outreach department of Cal Poly Humboldt that provides a variety of academic, professional development and personal enrichment opportunities. While the CEEE programs are open to almost everyone, there is an emphasis on providing access to those community members who are not matriculated students at the university. Non-matriculated students may take some regular university courses through the CEEE Open University program. High school students may take regular university courses through the CEEE High School Concurrent Enrollment Program. Also, those aged 60 and over may take regular classes through the Over 60 Program. There are also a variety of online degree programs offered through the college. The CEEE also offers a wide range of diverse and eclectic programs. Examples include music and art programs for children, the Osher Lifelong Learning Institute for those aged 50 and over, foreign language classes, travel-study programs, continuing education for teachers, MFT/LCSW, nurses, and law enforcement. In 1998 Humboldt State University opened the HSU First Street Gallery in Old Town Eureka, expanding community access to the university's cultural and fine arts programs. In 2007, the university further expanded its presence in Eureka with the opening of the HSU Humboldt Bay Aquatic Center, a $4.5 million aquatic facility on the bay in Old Town Eureka. Future plans include a new HSU Bay and Estuarine Studies Center. This new facility will be closer to the Coral Sea (in 2012 docked at Woodley Island, Eureka), the only vessel in a U.S. educational institution solely dedicated to undergraduate research. The new facility would be considerably larger than the other existing facility, the Fred Telonicher Marine Laboratory in Trinidad, 20 miles (32 km) north.

Cal Poly Humboldt Professor Steve Sillett has conducted groundbreaking research on redwood forest canopies and was featured in a 2009 cover story in National Geographic. He holds the Kenneth L. Fisher Chair in Redwood Forest Ecology, the only endowed chair in the world dedicated to a single tree species.

The Humboldt Energy Independence Fund (HEIF) is unique to the CSU, and uses student fee money to fund renewable energy and energy efficiency projects on campus. HEIF provides a rare opportunity for students, faculty, and plant operations staff to work together collaboratively towards a goal of a lower-carbon and energy-independent future. Compost and recycling bins are more common on campus than trash cans and many events are encouraged to be zero waste, all coordinated through the student-run Waste Reduction and Resource Awareness Program (WRRAP). The Associated Students fund WRRAP, the Campus Center for Appropriate Technology, and the Sustainable Living Arts and Music Festival (SLAM fest).

Cal Poly Humboldt built the first building in the CSU system to be LEED-gold certified for its eco-friendly features. The Behavioral and Social Sciences Building has facilities for rainwater collection and sustainably harvested wood native-plant landscaping, among others.

The university's location affords students the potential for outside activities in local parks and public lands, which include miles of accessible, undeveloped coastline. Rivers, streams, mountains, coastal redwood forests, and extraordinary terrain surround the university.

There are over 200 clubs on campus; these include a variety of options that range from social interests, academic, Greek life and sports.

The university has multiple publications. The Lumberjack is the university's only student-run weekly newspaper.

The university also has a monthly student-run newspaper, El Leñador, which is bilingual and produced by students with minority backgrounds. El Leñador received first place in competing against other monthly and bi-weekly papers from four- and two-year colleges and universities across California.

Osprey is the university's student-run magazine, published twice annually. It has won first-place awards in major regional competitions, including the Society of Professional Journalists' "Mark of Excellence" Awards and the California Intercollegiate Press Association awards.

Cal Poly Humboldt is also the only university in the CSU system to have a university press. The Press at Cal Poly Humboldt publishes high-quality scholarly, intellectual, and creative works by or in support of the campus community.

As of 2022, 2,069 beds were available on campus. As Cal Poly Humboldt enrolls nearly 6,000 students and as there is an acute housing shortage in Arcata, homelessness is prevalent among the student population. The university has sought to restrict and penalize students who are forced to live in cars, RVs or vans on campus. A 2018 study concluded that almost 20% of Cal Poly Humboldt students had experienced recent homelessness, double the rate of the CSU system as a whole.

University housing consists of six living areas: The Hill, Cypress, and Canyon for first-year students, and the College Creek Apartments, Campus Apartments, Creekview, and Cypress for other students. To address a housing shortage, Cal Poly Humboldt contracted with four local hotels—the Motel 6, Super 8, Ramada Inn, and Comfort Inn—to provide approximately 350 beds of "bridge housing" to students. By 2023, however, the university eliminated three of the four options, leaving only the Comfort Inn as the only motel option. A new off-campus housing complex, Craftsman Mall, will house a thousand residents and is projected to open in fall 2025; new on-campus housing for an additional 600 to 700 students is projected to open in summer 2027.

The Klamath River is the focus of the Klamath Connection, which is designed to help freshmen learn important skills for future science careers.

The Y.E.S. House (Youth Educational Services) programs are created by students and led by student volunteer programs. The Y.E.S. House serves the community. There are currently 17 programs running. Students can volunteer for these programs, and may also become directors.
