The University of Colorado Denver (CU Denver) is a public research university located in downtown Denver, Colorado. It is part of the University of Colorado system. Established in 1912 as an extension of the University of Colorado Boulder, CU Denver attained university status and became an independent institution in 1973. CU Denver is classified among R1: Doctoral Universities – Very High Research Activity. The university's graduate programs award more master's degrees than any other institution in the state, serving roughly 5,000 students annually. CU Denver makes up one-third of the Auraria Campus in downtown Denver, along with the Metropolitan State University of Denver and the Community College of Denver.

The University of Colorado created the Department of Medicine and Surgery in September 1883 in the Old Main building on the Boulder campus. The Department of Nursing opened in 1898.

By 1892, the last two years of classes were taught in Denver because the larger population afforded more practical experience. This practice triggered something of a turf battle with the University of Denver's medical school and the subsequent legal battle went to the state Supreme Court. In 1897, the court found that CU's charter restricted them to Boulder. However, in 1910, CU got an amendment to the state Constitution passed which allowed them to move back to Denver. In 1911, the School of Medicine combined with the Denver and Gross Medical College to form a larger school with a more comprehensive program, paving the way for the school's permanent move to Denver. In 1925, the School of Medicine moved to the campus on Ninth Avenue and Colorado Boulevard in Denver. This would become the University of Colorado Health Sciences Center (UCHSC).

In 1995, the Fitzsimons Army Medical Center was officially put on the Base Realignment and Closure list, after which officials from the Health Sciences Center, University of Colorado Hospital and the City of Aurora presented a proposal to the Department of Defense in Washington, D.C. to repurpose the decommissioned base as an academic health center. In 1999, the Army base was closed under the 1995 Base Realignment and Closure action. In 2004, the first UCHSC labs moved from Denver to the research towers on the Fitzsimons campus. In 2006, the Fitzsimons campus of UCHSC was renamed the Anschutz Medical Campus in recognition of philanthropic donations from Philip and Nancy Anschutz. By the end of 2008, academic and research operations of all CU Denver health sciences schools and colleges relocated from the Ninth Avenue and Colorado Boulevard campus to the new Anschutz campus, joining the affiliated University of Colorado Hospital and Children's Hospital.

The University of Colorado Denver began as the Extension Center of University of Colorado's Department of Correspondence and Extension, which was established in 1912. In 1938, the Extension Center acquired permanent quarters in Denver in the C.A. Johnson Building at 509 17th Street, where a single, full-time faculty member ran the school with the help of part-time teachers. In 1947, the Extension Center moved into the Fraternal Building at 1405 Glenarm Place. In 1956, the university acquired the Denver Tramway Company Building at 14th and Arapahoe Streets (now the Hotel Teatro and the Denver Center for the Performing Arts Tramway building). In 1964, the Extension Center was renamed the University of Colorado – Denver Center. On January 11, 1973, lawmakers, upon proclamation of the governor, amended the state constitution to establish additional CU campuses, transforming the University of Colorado—Denver Center into the University of Colorado Denver (CU Denver).

Between 1973 and 1976, the State of Colorado built the Auraria Higher Education Center (AHEC) on a 127-acre (0.51 km) downtown campus to be shared by the University of Colorado Denver, the Metropolitan State University of Denver and the Community College of Denver. In 1977, the Denver campus expanded to the newly opened AHEC, and later to several buildings extending into downtown Denver.

In the summer of 2004, the University of Colorado Denver and the University of Colorado Health Sciences Center merged to create the University of Colorado Denver and Health Sciences Center (UCDHSC). On October 29, 2007, the board of regents voted to rename UCDHSC the "University of Colorado Denver", consisting of the Anschutz Medical Campus and the Denver Campus. In August 2011, the regents approved a name change to the "University of Colorado Denver | Anschutz Medical Campus" (including the vertical bar), while the legal name of the dual institution remained "University of Colorado Denver".

However, in 2014, the University of Colorado appointed separate chancellors for the University of Colorado Denver and the University of Colorado Anschutz Medical Campus, effectively separating the two campuses. The campuses offer some dual campus programs, but the Anschutz Medical Campus is independently referred to as "CU Anschutz" or "CU Anschutz Medical Campus" in official materials, and the Denver Campus is independently referred to as "CU Denver" in official materials. The marketing campaign ALL FOUR:COLORADO emphasizes the distinct identities of the Denver and Anschutz campuses alongside the other CU institutions, Boulder and Colorado Springs.

The university was known for its association with Beall's List, created by its former faculty member Jeffrey Beall and used by universities worldwide, and ultimately for the role the university played in the disappearance of the list. In an interview in 2018, Beall stated that "my university began to attack me in several ways. They launched a research misconduct investigation against me (after seven months, the result of the investigation was that no misconduct had occurred). They also put an unqualified, mendacious supervisor over me, and he constantly attacked and harassed me. I decided I could no longer safely publish the list with my university threatening me in these ways."

CU Denver, part of the Auraria Campus, is located to the southwest of downtown Denver in the Auraria Neighborhood, on Speer Boulevard and Auraria Parkway. In a unique arrangement, CU Denver shares certain facilities (such as the Tivoli Student Union) on the Auraria Campus with two additional institutes of higher education, Metropolitan State University of Denver and the Community College of Denver. Proprietary facilities such as the CU Denver Student Commons Building are not shared. CU Denver Regional Transportation District's (RTD) Light Rail has two stops on the Auraria Campus: Colfax at Auraria and Auraria West Campus.

A student wellness center opened in Summer of 2018.
