The Saab 105 is a Swedish high-wing, twinjet trainer aircraft developed in the early 1960s as a private venture by Saab AB. The Swedish Air Force, which had opted to procure the type for various roles, issued the aircraft with the designation Sk 60. The Sk 60 entered service in 1967, replacing the ageing De Havilland Vampire fleet.

Saab AB, with subsidiaries collectively known as the Saab Group, is a Swedish aerospace and defense company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken primarily in Linköping.
