Oita Trinita(大分トリニータ,Ōita Torinīta?) is a Japanesefootball club currently playing in the J. League Division 2 team. The team name Trinita can be considered either a combination of the English word trinity and Ōita, or the Italian word trinità. The dual meaning expresses the will of the citizens, companies, and local governments to support the team.

The team started as Oita Trinity in 1994 and advanced through the Ōita Prefectural League, Kyushu League and finished as the runner-up at the 1996 National League, resulting in promotion to the JFL. In 1999, they changed their name to Trinita due to a copyright infringement, joined the J2 league and placed third. The team also placed third in 2000, and despite being in competition for promotion till the last game, it finished in sixth the next season. The following year, it won the J2 league championship and finally earned promoted to the J1 league. In 2008, they won J. League Cup, the first major title won by a Kyūshū club since the former Yawata Steel club's wins of Emperor's Cup in the 1960s.
In 2009 season, they suffered worst-ever results in their seven-year J1 history, including 14-game straight loss for league matches, which is the current worst record of J. League since Golden goal system is eliminated, at the earlier stage. They even fired cup-winning manager Pericles Chamusca in mid July. On October 25, their relegation to J2 from 2010 season is determined after being held to a 1-1 draw by ten-man Kyoto Sanga F.C.. Though, according to J.League's regulation, Oita would face relegation anyway due to the acceptance of official funding (by the regulation, any team receive this funding will not be allowed staying in Division 1, unless paid back in the future).
