The Alon A-4 is a prototype American light aircraft of the 1960s.

Alon INC. of McPherson, Kansas was formed by two former executives of Beechcraft in 1963 and had initially built an improved version of the ERCO Ercoupe as the Alon A-2.

It was a conventional, singled-engined low-winged monoplane of all-metal construction with a fixed (non retractable) tricycle landing gear undercarriage.

Alon produced one prototype, this first flying on February 25, 1966.
