Chandler is noted for its annual Ostrich Festival. Initially, agriculture was the primary business in Chandler, based on cotton, corn, and alfalfa. During the 1910s, there were ostrich farms in the area, catering to the demand for plumes used in women's hats of the era. This demand ebbed with the increasing popularity of the automobile, but the legacy of the ostrich farms would be commemorated by the Ostrich Festival. The Chandler Center for the Arts, a 1,500-seat regional performing arts venue, is located downtown, and the Arizona Railway Museum is at Tumbleweed Park.
