Sven Fornling (born 8 December 1988) is a Swedish former professional boxer. He held the IBO light-heavyweight title from 2018 to 2019 and challenged for the WBA interim light-heavyweight title in 2019.
Fornling challenged IBO light-heavyweight champion Karo Murat at Alsterdorfer Sporthalle in Hamburg, Germany, on 15 December 2018. He knocked his opponent to the canvas in the first round and was himself floored in the 12th round. Murat was deducted a point in round 11 for rabbit punches and Fornling went on to win via unanimous decision.
He made the first defense of the title against Dominic Boesel at Halle Messe Arena in Halle, Germany, on 16 November 2019, with the vacant WBA interim light-heavyweight title also up for grabs. Fornling lost by stoppage in the 11th round. He was taken to hospital following the fight where he was diagnosed as having suffered a brain hemorrhage.
Fornling announced his retirement from professional boxing in March 2020.
