Description Bangor Celtic F.C. are an Irish association football club based in Crumlin, Dublin. They play in the Leinster Senior League Senior Division.
Bangor Celtic were founded in 1987 as a breakaway club from Cashel Villa. They originally located themselves at the playing field of Good Shepherd School in Rathfarnham shortly after the breakaway. They first entered the FAI Cup in 1999. In the 20th century, the club later moved to Iveagh Grounds in Crumlin, South Dublin. Bangor Celtic have been used as a feeder club to the League of Ireland Premier Division side Bohemians. They won their first Leinster Senior League Senior Division league title in 2005 and then won it again in 2009.
In 2019, Bangor Celtic merged with nearby Greenhills/Greenpark F.C. The club decided that they would not locate themselves at the Iveagh Grounds and instead moved to Greenhills/Greenpark's ground due to superior facilities. The Greenhills Boys section of the club was kept separate from the merger. The newly merged club would be renamed Bangor Greenhills/Greenpark F.C. (Bangor GGFC for short) and would continue to play in the Leinster Senior League. The merger was made as part of a trend of smaller Dublin football clubs merging to concentrate talent and be able to challenge larger junior clubs like Crumlin United and Cherry Orchard. It also allowed the clubs to share sponsorship with Bangor Celtic's agreement with Permanent TSB being transferred over to the new club. In 2022, the club returned to it's former name of Bangor Celtic F.C. and updated the club crest to reflect the change.
The club play their Sunday games at the Transport Club and their Saturday matches in Beechfield Park.
