# Joseph Patrick O'Brien

Joseph Patrick O'Brien (born 23 May 1993) is an Irish horse racing trainer and former flat racing jockey. He is the son of trainer Aidan O'Brien. In 2012 he rode Camelot to win the 2,000 Guineas, the 2012 Epsom Derby and the Irish Derby.

## Riding career

O'Brien won a bronze medal at the 2009 European Pony Championships and was one of three jockeys who shared the Irish champion apprentice jockeys' title in 2010. He rode his first winner on Johann Zoffany, trained by his father, at Leopardstown Racecourse on 28 May 2009 and gained his first classic success when Roderic O'Connor won the 2011 Irish 2,000 Guineas. In 2012 Aidan and Joseph, 19, became the first father-son/trainer-jockey combination to win The Derby, with Camelot.
He was Irish Champion Jockey in 2012 with 87 winners. In October 2013, O'Brien broke a 20-year-old record with a treble at Navan to get his 117th winner of the season and beat the previous record set by Mick Kinane. He finished the 2013 season with 126 winners and retained his Irish Champion Jockey title.
In March 2016 O'Brien announced that he would be stepping down from race-riding to concentrate on his new career as a trainer.

## Training career

O'Brien began his training career at Owning Hill, County Kilkenny. He made an immediate impact when Intricately, ridden by his younger brother Donnacha, won the Moyglare Stud Stakes in 2016. He went on to win the Melbourne Cup with Rekindling in 2017 and with Twilight Payment in 2020; the Irish Derby with Latrobe in 2018; and the Pretty Polly Stakes with Iridessa in 2019. He also trained several good winners under National Hunt rules.
