Ivica Trušček (born 15 December 1987) is a Croatian professional mixed martial artist who competes in the welterweight division. One of the most active fighters in European mixed martial arts, he has competed in more than 85 professional bouts since 2007 and has been described as the record holder for the most fights in the Balkan region. He is a former World Freefight Challenge (WFC) welterweight champion and has fought for promotions including Final Fight Championship, Cage Warriors, M-1 Global, Oktagon MMA and Fight Nation Championship (FNC).
Background Trušček is from the area of Križevci in northern Croatia. Unable to support himself through fighting alone, he worked part-time in his father's printing business while competing, training with American Top Team Zagreb when he could travel to the capital and otherwise practicing with his brother. In later years he worked as a truck driver during the week and as a security guard at weekends.
Mixed martial arts career Trušček made his professional debut in 2007 and fought at an unusually high frequency, entering the cage or ring 43 times between February 2010 and April 2016 alone. His opponents included several fighters who went on to compete in the UFC, among them Mairbek Taisumov, Piotr Hallmann and future UFC lightweight champion Islam Makhachev, who submitted Trušček at an M-1 Global event in September 2014.
Trušček twice fought the Danish welterweight Nicolas Dalby, losing decisions in August 2012 and March 2013; the second bout was accepted on four days' notice. The two became friends, and when Dalby faced Zak Cummings at UFC Fight Night 86 in Zagreb in April 2016, Trušček worked in Dalby's corner.
As World Freefight Challenge welterweight champion, Trušček defended the title against Sergei Churilov at WFC 17 in October 2012. He won the WFC welterweight title a second time by submitting Arber Murati at WFC 23 in February 2019. In October 2015 he knocked out Final Fight Championship welterweight champion Viktor Halmi in the first round of a non-title bout.
In February 2025 Trušček took a bare-knuckle boxing bout for the Croatian promotion FNC in Zadar. On 18 October 2025, at Oktagon 78 in Cologne, he defeated the German welterweight Christian Eckerlin by first-round technical knockout in the event's headline bout, an upset before a crowd of about 20,000 at Lanxess Arena that was broadcast on German television. In May 2026, aged 38, he challenged Kamil Kraska for the FNC welterweight championship in Belgrade, losing by second-round technical knockout.
