The Embraer EMB 120 Brasilia is a twin-turboprop commuter airliner, produced by Embraer.

It first flew on 27 July 1983, and entered commercial service in October 1985. Since 1994, manufacture has focused exclusively on the EMB 120ER, with extended range (1,575 km) and increased capacity. With its 30-passenger capacity (but nearly twice the speed), the Brasilia probably comes closer than any other aircraft to being a latter-day DC-3 replacement.

Most of the EMB 120s were sold in the United States and other places in the Western Hemisphere. Some European airlines such as Régional in France, DAT in Belgium, and DLT in Germany also purchased EMB-120s. Serial production ended in 2001. As of 2007, it is still available for one-off orders, as it shares much of the production equipment with the ERJ-145 family, which is still produced. The Angolan Air Force, for example, received a new EMB 120 in 2007.

The EMB 120 Brasilia and smaller EMB 110 Bandeirante are Embraer's only turboprop-driven aircraft in its civilian product line. SkyWest Airlines currently operates the largest fleet of EMB 120s under the United Express and Delta Connection brand.
