Urban Prep Academies (also known as Urban Prep Charter Academy for Young Men or simply Urban Prep) is a nonprofit organization that operates a network of free open-enrollment public all-male college-preparatory high schools in Chicago. Founded in 2002, and receiving its first charter approval from Chicago Public Schools in 2005, it operates the first all-male public charter high school in the United States. The network opened a second campus in 2009 and a third in August 2010. From 2010–2019, 100% of the seniors in the school's graduating classes were admitted to four-year colleges or universities.
