WASCA is the Washington Area Square Dancers Cooperative Association. It is an organization run by dancers for dancers, that includes members in the District of Columbia, Maryland, Delaware, Virginia, and West Virginia. WASCA includes square dance clubs, round dance clubs, and clogging groups.
WASCA was formed in October 1956 to provide an organizational structure to host a 1957 regional dance convention in the DC area. A second convention was hosted by WASCA in September 1958. The successful results of these efforts provided the enthusiasm to produce the first WASCA Spring Dance Festival in March 1960.
The annual Festival is held in March and is WASCA's highlight event of the year. It is one of the most popular Square and Round Dance Festivals of its kind in the nation, and attracts hundreds of dancers from other areas. The festival always features a first class lineup of the best callers and cuers in the nation. Since 2006 the WASCA Spring Festival has been held at the Hilton Alexandria Mark Center Hotel in Alexandria, Virginia. In 2025 it will be held at the Hilton Washington Dulles Airport Hotel in Herndon.
