The Aero L-60 Brigadýr (Czech: Brigadier) was a small, high-wing propeller-driven Czechoslovakian STOL utility aircraft developed for both civil and military use. A prototype, designated XL-60, with Argus As 10C engine, first flew on December 24, 1953, but it was not successful. The plane was thoroughly redesigned and the second improved prototype, with M-208B flat-six engine, flew on June 8, 1954. The aircraft's configuration bears a strong resemblance to the Fieseler Fi 156 "Storch" licence-produced in Czechoslovakia during and after World War II (as K-65 Čáp), and which this aircraft was intended to replace. By the end of production in 1960, 273 had been built by Aero, including an improved version, the L-160 with an all-metal tail.

Aircraft retrofitted with a PZL-built Ivchenko AI-14R radial engine are known as the L-60S.
