Tritonville Football Club was an association football club from Dublin, Ireland. They competed for one season (1912–13) in the Irish League, one of only three Dublin clubs to do so; they also competed in the Irish Cup. Tritonville played their games on grounds which were used by the GAA on Sundays for Gaelic games; as a result this attracted much controversy from the Belfast-based Irish Football Association who favoured Sabbatarianism.
