Peninsula Gaming, LLC was a casino operator based in Dubuque, Iowa, with five properties in Iowa, Louisiana, and Kansas.
In February 2002, Peninsula bought a fifty percent interest in the Evangeline Downs racetrack in Lafayette Parish, Louisiana from B. I. Moody for $15 million. They bought the remaining half several months later from William Trotter for another $15 million, plus 0.5% of slot revenues for the first ten years. After Lafayette voters had rejected slot machines at the track, Evangeline Downs had planned a move to St. Landry Parish, which Peninsula carried out. The casino at the new site opened in late 2003, with races following in 2005.
