Hedgehunter (born 25 January 1996) is an Irish race horse, who won the 2005 Grand National steeplechase, ridden by Ruby Walsh and trained by Willie Mullins.

He made one more racecourse appearance that season finishing second to the Royal and Sun Alliance Chase winner Rule Supreme at the Punchestown Festival.

He began the 2004-2005 season chasing home the classy Strong Flow to finish fourth in the Hennessy Gold Cup at Newbury Racecourse.

The race began at a furious pace and despite making a slight mistake at the tenth fence and Ruby Walsh almost losing his irons Hedgehunter was chasing the well fancied Clan Royal.

Starting 5/1 joint favourite for the 2006 National, Hedgehunter carried top weight of 11 stone 12 (166 lb, 75 kg) and came off of a hard race a few weeks earlier when he finished second in the Cheltenham Gold Cup.
