Holly McPeak is an American former beach volleyball player. McPeak started out at Cal Berkley, but eventually ended up at UCLA, where she won a NCAA National Title in her senior year.

A three-time Olympian, McPeak garnered 72 career beach volleyball titles with career earnings of $1.4 million USD. She is third in titles won (behind Misty May-Treanor and Kerri Walsh) and second in career earnings (behind May-Treanor) for female professional beach volleyball players. She won a bronze medal at the 2004 Summer Olympics with partner Elaine Youngs. Though McPeak was considered short for a beach volleyball player at 5 feet 7 inches in height, she was one of the toughest players to beat on the tour. She had a long career, and had at least one career victory every year from 1993 to 2004, with the exception of 1998, when there was no women's domestic tour. On October 30, 2009, McPeak was inducted into the Volleyball Hall of Fame.

Since retiring from beach volleyball, McPeak works as a color commentator for Pac-12 volleyball shown on Fox Sports West, including most televised games of UCLA. She also does color for SEC coverage on the SEC Network. In 2014, McPeak served as a sand volleyball game analyst for Pac-12 Network.
