The Embraer EMB 121 Xingu (pronounced "shingoo") is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design of this plane is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on October 10th, 1976.

A modified form of the EMB 121, the EMB 121A1 Xingu II, was introduced on September 4th, 1981 with a more powerful engine (PT6A-135), increased seating (8 or 9 passengers) and a larger fuel capacity.

Before production ceased in August 1987, Embraer had produced 106 EMB 121 aircraft, 51 of which were exported to countries outside Brazil. Currently, the French Air Force is the largest operator with 23 aircraft still in service.
