Gordon D'Arcy (born February 10 1980) is an Irish rugby union player, more specifically an outside centre. He plays his club rugby for the Celtic League side Leinster.

D'Arcy made his Ireland debut on October 15 1999 as a substitute against Romania during the World Cup. However, following complaints about his attitude by his teammates, complaints which almost drove him to retire from the game, D'Arcy was left out of the international setup for three years. D'Arcy's second game for his country came on November 17 2002 as a late substitute in Ireland's 64-17 win over Fiji. He made a further three appearances as a substitute during 2003.

On the eve of the 2004 Six Nations Championship D'Arcy was granted a place in Ireland's starting line-up for the first time. During the tournament his form was such that he ousted captain Brian O'Driscoll as outside centre, forcing his Leinster teammate to play at inside centre following his return from injury. D'Arcy was voted player of the tournament as he inspired his country to the Triple Crown for the first time since 1985.

He was named to the British and Irish Lions squad for their 2005 tour to New Zealand.
