Dougie Costello (born Ireland Co Galway, 1983) is a Group 1 winning Irish jockey.
He is one of the few jockeys to have won at the top level in both codes - the 2012 Triumph Hurdle at the Cheltenham Festival on Countrywide Flame, and the 2016 Commonwealth Cup on Quiet Reflection at Royal Ascot.

Burke ended his partnership with Costello in May 2017, saying "things didn't quite pan out as I'd hoped".
Costello vowed to work twice as hard to get other big race victories.
