Fotbal Club Delta Tulcea, commonly known as Delta Tulcea, is a football club from Tulcea, Romania, originally founded in 1973, then refounded in 2005, 2013, and 2021. The club is enrolled in the Liga IV – Tulcea County, fourth tier of the Romanian football.
The club was founded in 1973 as Fotbal Club Delta Tulcea then reorganized in 2005. The club's first president in the new format was Petre Marinescu since 20 May 2006.
In their first season after the reorganization, the team played in the Romanian third league, where they would win the league's second series by a margin of twenty points from the runner-up, CSM Râmnicu Sărat. The manager behind this success was Constantin Gache.
After having promoted to the second league, with the addition of a few new players, and the same coach, the team would go on to winning the second league in the 2006–07 season after managing an eight-win streak. Even so, the team would not promote to Liga I due to licensing problems.
It is due to this that the team would lose some of its valuable players at the time, and also its coach that went to the rival team Farul Constanța.
After this, they played in the Liga II until their dissolution in the summer of 2013. The club was refounded as Delta Dobrogea Tulcea in the same year.
Delta withdrew from Liga III during the 2018–19 season after a 60 points penalization due to financial problems, but continue to be active at youth level.
On August 27, 2022, Tulcenii announced that the club will not enroll for the 2022–23 season of Liga IV - Tulcea County due to the financial and organizational problems, but they will continue to focus on youth football.
