Coughlin–Alumni Stadium is a stadium in Brookings, South Dakota, United States, on the campus of South Dakota State University. It is the home venue of the South Dakota State Jackrabbits football team. The stadium opened in 1962 and currently seats 16,700 spectators. In 2014, a proposal for a new football stadium was approved, and construction began on Dana J. Dykehouse Stadium, which is being built in two phases on the site of Coughlin–Alumni Stadium. New seating on the east and south sides of the stadium was completed for the opening of the 2015 season, which increased seating capacity from the original 15,000. Following the 2015 season, the main grandstand of Coughlin–Alumni Stadium will be torn down to make way for completion of the new west grandstand and press tower, which is under construction, and a new playing field with artificial turf will be built on the existing field. The new stadium is slated to be completed by the beginning of the 2016 season.
