The Air Tractor AT-500 is a family of agricultural aircraft that first flew in the United States on 25 April 1986, manufactured by Air Tractor Inc. Of monoplane low-wing, taildragger configuration, they carry a chemical hopper between the engine firewall and the cockpit. Compared with their predecessor, the AT-500 family featured a wingspan increase of 50 ft (15.2 m), and an additional fuselage stretch of 22 in (56 cm), allowing for a larger chemical hopper. Almost all variants offer a widened "buddy" seat or a tandem seat for a passenger, observer, or loader; trainer aircraft with full dual controls have also been offered.

From 2011 through 2018, the AT-502B was the world's top-selling agricultural aircraft with 388 deliveries, while the combined AT-500 line (AT-502A, -502B, and -504) was among the world's most popular fixed wing general aviation single-turboprop aircraft families, with 470 delivered—a total exceeded only by the Pilatus PC-12 and the Cessna 208 Caravan family during that time.
