Misty E. May-Treanor (born July 30, 1977) is an American professional beach volleyball player. She has won more tournaments than any other female player with 103 career wins. May-Treanor and teammate Kerri Walsh were the gold medalists in beach volleyball at both the 2004 and 2008 Summer Olympics. They have been called "the greatest beach volleyball team of all time". May-Treanor is the daughter of Bob "Butch" May, a member of the 1968 US volleyball team and prominent beach player, and Barbara May, a nationally-ranked tennis player who later transitioned to beach volleyball. Barbara died of cancer in 2002. A prominent tattoo on Misty's shoulder, an angel with the initials "B.M.", is a reminder of her mother.
Misty shares a tattoo with her husband, Detroit Tigers player Matt Treanor, that is of a M-squared. She is a fan of and childhood friends with basketball star Jason Kidd, who was in the stands when May-Treanor and Walsh defended their gold medal in Beijing. The tattoo of a roman numeral five on her lower back is her retired number from school and the initials are a tribute to her grandmother.
