Citrus College is a public community college in Glendora, California. The Citrus Community College District, which supports the institution, includes the communities of Azusa, Claremont, Duarte, Glendora, and Monrovia.

Citrus Union High School was founded in 1891 to serve Azusa and Glendora. In 1915, educator Floyd S. Hayden expanded its offerings to include a junior college, and, from 1915 to 1961, the school was operated by the Citrus Union High School District as both a high school and a junior college. Citrus College is the oldest community college in Los Angeles County, California, and the fifth oldest in the state of California.

During the 2019-2020 academic year, Citrus College enrolled 19,626 students. It conferred 2,444 degrees and awarded 2,175 certificates. 531 students graduated with honors (GPAs of 3.3 to 4.0).

Its operating budget for 2020-2021 is $78 million.

In 2003, at California's Citrus College, under the pressure of litigation and FIRE's national campaign for campus constitutional rights, the Board of Trustees voted to rescind most of the speech codes at the public institution. This was the first victory in FIRE's declared war on speech codes at public colleges and universities.

The following year, Citrus College was sued again by FIRE when Citrus College reinstated its policy in the early 2010s, when a Young Americans for Liberty chapter, led by Gabriel Nadales and Vincenzo Sinapi-Riddle, was threatened with sanctions for not staying inside the "Free Speech Zone." In an interview to the San Gabriel Valley Tribune, Greg Lukianoff, the president of Foundation for Individual Rights in Education, said, "'Citrus College agreed to eliminate its restrictive 'free speech zone' in the face of a FIRE lawsuit back in 2003, but later reinstated its speech quarantine when it thought no one was watching'...'But FIRE was watching, and we'll continue to do so. If the speech codes come back again, so will we.'"
