Pleascach (foaled 6 February 2012) is an Irish Thoroughbred racehorse whose wins included the Irish 1000 Guineas and the Yorkshire Oaks. Bred and trained by Jim Bolger she showed promise in two starts as a two-year-old in 2015, finishing fourth in a Group Three race on her debut and then winning a maiden race. In the spring of 2016 she finished second on her first appearance, won the Blue Wind Stakes and then defeated Found in the Irish 1000 Guineas. In summer she was beaten by Curvy in the Ribblesdale Stakes and disappointed in the Pretty Polly Stakes before returning from a lengthy absence to win the Yorkshire Oaks. On her final racecourse appearance she finished fourth in a top-class international field for the Irish Champion Stakes.
