Karapet Muradyan (; born 2 September 1983), best known as Karo Murat (), is a German-Armenian professional boxer who held the IBO light-heavyweight title in 2018. He also held the European super-middleweight title from 2008 to 2009 and the light-heavyweight version in 2017.
Murat made his professional debut in Hessen, Germany on 23 September 2006 defeating Matus Sestak.
On 16 February 2008, he defeated Sergey Kharchenko at the Nuremberg Arena to lift the EBU-EE super middleweight title via stoppage in the 10th round.
In his next fight, Murat travelled to Neubrandenburg to fight for the full European belt against Cristian Sanavia on 12 April 2008, winning by unanimous decision.
A first defence in Bielefeld on 20 September 2008 resulted in a majority points win over Spain's Gabriel Campillo. He then met Sanavia in a rematch on 28 February 2009, again in Neubrandenburg. Murat stopped Sanavia in the 10th round to register a second successful defence of the title.
Murat moved up to light-heavyweight and fought Serhiy Demchenko to win the vacant WBO Inter-continental light-heavyweight title via unanimous decision on 29 August 2009 in Halle.
His first defence against Guyana's Sean Corbin resulted in a second round stoppage win on 30 January 2010. Murat successfully defended his title once more on 1 May 2010 beating Tommy Karpency over 12 rounds, knocking him down in the second, in Oldenburg, Germany.
On 18 September 2010, Murat faced Nathan Cleverly in a WBO light-heavyweight title eliminator. The bout was waved off by the referee as the 10th round was about to start on the advice of the ringside doctor.
He rebounded from the defeat on 12 February 2011 with an eight round points win over Christian Cruz and followed this on 7 May 2011 by winning the IBF Inter-continental title against American boxer Otis Griffin with an 11th round stoppage. He made his first defence of the title in a rematch against Gabriel Campillo on 1 October 2011, with the fight ending in a draw.

He was knocked to the canvas in the first round and floored his opponent in the 12th round. Murat was deducted a point in round 11 for rabbit punches and Fornling went on to win via unanimous decision.
