Igor Kollár (born 25 June 1965 in Žiar nad Hronom, Banská Bystrica Region) is a retired male race walker from Slovakia. He is a three-time Olympian.

At the 1996 Olympics, Kollár garnered a "huge lead" over the pack in the 20 km walk, but he was disqualified as the judges deemed that he held two feet off the ground. Kollár claimed that the judges disqualified him because he was so far ahead, and they just wanted a closer finish. Following the '96 Olympics, Kollár's performance lagged and he was eventually expelled from his Dukla Banská Bystrica club, with the club saying that he was "too old". In response, Kollár created his own club called HITEC and he continued to compete for several years, making a resurgence at the 1999 World Championships where he finished 6th.^[1]
