Bogside Racecourse was a horse racing track situated in Irvine, Scotland, on the banks of the River Irvine. Its first meeting was held on 7 June 1808, and its last on 10 April 1965, although there is evidence of an event known as the Irvine Marymass Races in the area as far back as 1636, initiated by the Earl of Eglinton. During its existence it hosted the Scottish Grand National (now contested at nearby Ayr) and twice hosted the National Hunt Chase Challenge Cup which now takes place at the Cheltenham Festival. Its other major race was the Bogside Cup.
