John O'Quinn Field at TDECU Stadium is an American football stadium on the campus of the University of Houston. The stadium serves as the home of the Houston Cougars football team, which represents the University of Houston in collegiate football. TDECU Stadium was built on the former site of Robertson Stadium, which was the intermittent home of the school's football program since 1946. Its official name is derived from Texas Dow Employees Credit Union (TDECU), the largest credit union in Houston, which purchased its naming rights in the largest-ever naming rights deal for a college football stadium.
