Tom Gullikson (born September 8, 1951) is a tennis coach and former professional tennis player born in La Crosse, Wisconsin and raised in Onalaska, Wisconsin in the United States.

Gullikson also won the mixed doubles title at the US Open in 1984, with Manuela Maleeva.

Gullikson's best performance at a Grand Slam came when he got to the quarter-finals of the 1982 US Open, defeating John Alexander, Jérôme Potier, Chip Hooper and Jaime Fillol before losing to Guillermo Vilas.

Gullikson played compatriot John McEnroe during the first round of the 1981 Wimbledon championships, when the latter got into a verbal altercation with the umpire, during which he uttered his infamous "You cannot be serious!"

From December 2001 to February 2002, Gullikson briefly coached Pete Sampras.
