The PA-31 Navajo is a family of cabin-class, twin-engine aircraft designed and built by Piper Aircraft for the general aviation market, using Lycoming engines. It was also licence-built by Embraer as the EMB 820.

In the mid-1960s company founder William T. Piper started development of the PA-31. Targeted at small-scale cargo and feeder liner operations and the corporate market, the aircraft was a success. It continues to prove a popular choice, but due to greatly decreased demand across the general aviation sector in the 1980s, production of the PA-31 ceased.
