John Roddick (born July 1, 1976) is an American former professional tennis player and the present coach of Andy Roddick.

Born in San Antonio, Texas, he is the older brother of tennis star Andy Roddick. Though his playing career was not quite as successful as that of his younger brother, John was a world-class player in his own right. John went on to be four time All American at the University of Georgia from 1995-1999 and was named UGA Athlete of the Year in 1998. He was a top US junior and was ranked as high as #6 internationally in singles, and #3 internationally in doubles. However a back injury ultimately put a stop to John's professional career and he turned his attentions to coaching.

John travels with Andy quite a bit but spends time at his junior tennis academy at Roddick Total Tennis. He leaves the day-to-day development coaching to Myron Grunberg, who worked for the Canadian Tennis Federation for many years and also traveled with Canadian professionals on the tour. With former Roddick students Nate Schnugg and Jamie Hunt now at Roddick's alma mater Georgia, and Kellen Damico and Tyler Hochwalt elsewhere while they await their entrance to the University of Texas and University of Florida respectively, the marquee players at the academy are Vlad Ignatic of Belarus who is the 2007 French Open Junior champ and Alexey Grigorov of Russia, both whom have been associated with the academy for several years.
