The Austin City Limits Music Festival (ACL Festival) is an annual three-day American music festival that takes place in Austin, Texas at the city's central public park, Zilker Park. Each year, in addition to food & art, most from local vendors, ACL Festival brings together more than 130 acts from all over the world to play rock, indie, country, folk, electronic and more on eight stages. Over 70,000 fans attend the festival each day.

Named after the legendary PBS concert series, the Festival is produced by Austin-based C3 Presents, who also produce Lollapalooza. In 2011, ACL Festival celebrates its 10th Anniversary on September 16–18.
