The Willowfield club, associated with and funded by the Willowfield Unionist Club, existed from at least 1889, and it turned senior in 1918. In the 1927–28 season, it became the first from outside the
Irish League to win the
Irish Cup since the League's formation in 1890. It defeated
Larne 1–0 in a replay at
Windsor Park, the Willows having held the lead in the first game from the 40th to the 85th minute. Willowfield had previously reached the Irish Cup final in 1923–24, when it lost 1–0 to
Queen's Island (again at Windsor Park), the winning goal coming as early as the 2nd minute. The club played in the Irish Intermediate League from 1921. However the club struggled with finance through the 1920s and folded in 1930. A new amateur club with the same name was founded in 1932 and its greatest success was winning the
Clarence Cup in 1935–36, beating Malone R.C. 3–0 in the final. ==Colours==
