The Atlanta Lawn Tennis Association (ALTA) is a non-profit organization devoted to the development of tennis for recreation and physical fitness and is pledged to maintain the rules of play and high standard of sportsmanship. The primary function of ALTA is scheduling league play for adult teams and junior teams in the five-county metro area. A facility annexation program was developed in 1988 to include qualifying facilities in counties adjacent to the metro counties.

ALTA is affiliated with the United States Tennis Association (USTA) through membership in the Southern Tennis Association (STA) and abides by the USTA rules of tennis and code of play.

Volunteer officers comprise the Board of Directors and the Executive Committee who in turn direct over 200 league coordinators and a paid office staff of seven people. ALTA publishes a bi-monthly magazine, Net News.
