FC Inter Turku has a nickname that points to its origins: the club is also known as Hinaajat, the Tugboats. It was founded in 1990 by Stefan Håkans, managing director of the Turku towage and salvage company Alfons Håkans. According to the club's own story, he started it after his 11-year-old son could not find a place in any of the other youth teams in the city. Football Club International Turku began as a youth side, and its senior team was formed in 1992 at the fourth level of the Finnish league system.
The rise through the divisions was quick. Inter won the Ykkönen, the second tier, in 1995 and has played in the Veikkausliiga since 1996, apart from one season. It finished last in 1997, was relegated, and went back up the following year. In 1996 both Turku clubs were in the top flight for the first time, and the local derby against TPS drew a then record crowd of 8,200. The rivalry with TPS has been the club's defining local fixture ever since.
The greatest moment in the club's history came in 2008, when Inter won its first and so far only Finnish championship. The title was decided on the last day of the season, when Inter won 2–0 away at Jaro. Coach Job Dragtsma, a Dutchman, built the success on defence: the team conceded only 12 goals in 26 league matches. It won 15 games, drew 9 and lost 2, finishing with 54 points and ahead of Honka and Lahti. That spring Inter had also won the League Cup, beating TPS in the final, so 2008 was a year of two trophies. Inter has since finished second in the league several times, including in 2011, 2012 and 2025.
The championship brought a place in the 2009/10 Champions League qualifying rounds. Inter lost both legs of the second qualifying round 1–0 to Sheriff of Moldova and went out 2–0 on aggregate. Its European record consists mainly of qualifying ties. In 2005 it won an Intertoto Cup tie against ÍA of Iceland 4–0 on aggregate, and in 2022 it lost a Conference League qualifier to Drita of Kosovo, 3–1 on aggregate.
The national cup has produced three trophies, in 2009, 2018 and 2026. In the 2018 final, played at the Töölö football stadium in Helsinki, Inter beat favourites HJK 1–0. The decisive goal came about ten minutes from time from substitute Mikko Kuningas, and captain Timo Furuholm celebrated the first cup win in nine years. In 2026 Inter again beat HJK 1–0 in the final, this time with a goal in first-half stoppage time, to win the cup for the third time.
Inter plays at the stadium in the Kupittaa district of Turku, which opened in 1952 and is shared with TPS. It holds about 9,000 spectators. The club's colours are blue and black, which gave it the official nickname Sinimustat. A founder with a salvage business, a quick climb through the leagues and a local derby with TPS still define the identity of Inter Turku, which finished second in the league in 2025 and entered Europe again in 2026.
