Gregor Balažic (born 12 February 1988) is a retired Slovenian professional footballer who played as a central defender.

He made his first-team debut at the age of 17 in a 2–1 home league win against Zagorje on 30 April 2005, during the club's last competitive season.

In January 2011, Balažic signed with Karpaty Lviv in the Ukrainian Premier League, penning a four-year deal for €400,000 in what was the club's most expensive transfer ever.

On 25 April 2015, during the Eternal derby against Red Star Belgrade, Balažic was fouled in the area by Vukašin Jovanović in what should have been a penalty for Partizan, but referee Milorad Mažić did not concede it.
