Prince William Sound College (formerly Prince William Sound Community College and also known as PWSC and P-DUB) is a college located at 303 Lowe St. in Valdez, Alaska. PWSC comprises one main campus in Valdez and extension campuses in Glennallen and Cordova. The college is part of the University of Alaska Anchorage under the aegis of the University of Alaska System.

PWSC serves approximately 44,000 sq. mi., about the area of Ohio. Around 1,000 local, rural, and out-of-state students attend the college either face-to-face, through ITV classrooms or via Blackboard. There is no out-of-state tuition.

Dr. John Devens founded the college in 1978 with an endowment of $50,000 he requested from the City of Valdez. For fiscal year 2012, Valdez allocated $700,000 for the school.

Since 1989, the college has been housed in what was formerly Growden-Harrison Elementary School, built on the new Valdez town site soon after the 1964 Alaska earthquake. The three buildings in the dormitory complex were originally government housing. The college acquired them in 1977 for one dollar and fully renovated them in 2010.

PWSC instituted the Last Frontier Theatre Conference in 1993.

In 1998, Maxine Whitney donated a large collection of native artifacts to the college. The collection now resides in the Maxine & Jesse Whitney Museum, located on the PWSC campus.

In a cost-saving move, the University of Alaska Anchorage regents in 2014 requested the college drop its separate accreditation by the Northwest Commission of Colleges and Universities and come under UAA's accreditation. The commission approved the change in July, 2015. At the same time the college began the process of dropping "Community" from its name.
