The Intercollegiate Soccer Football Association (abbrevriated ISFA) was a sports government body that ruled the practice of college soccer in the United States from 1905 to 1958.

Before the NCAA held its first men's National Collegiate Soccer Championship in 1959, national champions were selected by a committee of the ISFA based on season records and competition. In addition, the College Soccer Bowl tournament was held from 1950–1952 (following the 1949–1951 seasons) for the purpose of deciding a national champion on the field. The Soccer Bowl was a one-site competition involving four teams selected by college soccer administrators. However, the ISFA committee continued to select the national champion in those three years (in 1950 selecting as champion a team that did not participate in the second Soccer Bowl).^[1]

College soccer started in Northeast colleges and at private schools in the late 19th century, while club soccer was mostly played in the Midwest and the South. In the West, Stanford started up a soccer program in 1911, University of San Francisco in 1932, and UCLA in 1937, playing largely amateur teams. In 1945, at the end of the world war, the ISFA had only 22 member college teams.^[2] This grew to over 50 by 1947.

From 1905 through 1925, the Intercollegiate Soccer Football League (an Ivy League forerunner) determined an annual champion in College soccer. The league was dissolved after the 1925 season when Harvard and Yale threatened to resign citing dissatisfaction with the organization and scheduling saying its took players away from their educational studies too frequently. The former league pledged to create a new representative soccer association that could help govern the sport at a collegiate level. Soon after the Intercollegiate Soccer Football Association was born offering an annual Outstanding Soccer Team award, the mythical national soccer championship, through 1935 and from 1946 through 1958.^[3][4]
