Brooklyn Celtic was a name used by at least two U.S. soccer teams. The first was an early twentieth century amateur team which was formed in August 1910 and dominated the New York Amateur Association Football League from 1912 to 1917. The second was a member of the professional American Football League in the 1930s and early 1940s. A third Celtic club from Brooklyn, St. Mary's Celtic replaced the second club in the ASL before the 1935/36 season.
