The Asian Football Confederation (AFC) is the governing body of association football, beach soccer, and futsal in most countries and territories in Asia. The AFC was formed in 1954. It has 47 members. The Asian Ladies Football Confederation (ALFC) was the section of AFC that managed women's association football in Asia. The group was independently founded in April 1968 in a meeting involving Taiwan, British Hong Kong, Malaysia and Singapore. In 1986, ALFC merged with AFC.
