PragerU, short for Prager University, is a conservative digital media nonprofit founded in 2009 by Dennis Prager and Allen Estrin. Based in the San Fernando Valley of Los Angeles, California, its mission is to promote conservative and libertarian viewpoints, focusing on Judeo-Christian values, free speech, capitalism, personal responsibility, and religious freedom.

The organization produces short educational videos, typically around five minutes long, covering a range of political, economic, social, and cultural topics from a conservative perspective. These videos are designed to be shareable and appeal to younger audiences, particularly high school and college students. PragerU has built a significant online presence, with billions of views and a strong following on social media. It also encourages student involvement through "PragerFORCE," an initiative that promotes its content on campuses. The organization is funded through donations, including contributions from wealthy conservative donors and small online supporters.
