Georges St-Pierre (French pronunciation:[ʒɔʁʒsɛ̃pjɛʁ]; born May 19, 1981), also known by his initials GSP, is a Canadian former professional mixed martial artist. He is widely regarded as one of the greatest fighters in mixed martial arts (MMA) history.[11] St-Pierre was a two-division champion in the Ultimate Fighting Championship (UFC), having won titles in the welterweight and middleweight divisions.
St-Pierre is a three-time former UFC Welterweight Champion, having won the title twice and the interim title once between November 2006 and April 2008. He was ranked as the #1 welterweight in the world for several years by Sherdog[12] and other publications.[13][14][15] In 2008, 2009 and 2010 he was named the Canadian Athlete of the Year by Rogers Sportsnet.[16][17][18]Fight Matrix lists him as the top MMA welterweight of all time and the most accomplished fighter in MMA history.[19] He was voted as the greatest pound-for-pound MMA fighter in history in The Athletic MMA fighter survey.[20]
St-Pierre retired as the reigning Welterweight Champion in December 2013, having held the record for most wins in title bouts and the second longest combined title streak in UFC history (2,204 days) while defending his title nine consecutive times. He also won a record 33 consecutive rounds between 2007 to 2011.[21] He returned to the Octagon in November 2017 at UFC 217, when he defeated Michael Bisping by submission to win the Middleweight title, thus becoming the fourth fighter in the history of the UFC to be a multi-division champion. He relinquished the title a few weeks later, citing health reasons, and officially retired from MMA.[22][23]
