The Aeronca Model K Scout is an American light airplane first marketed in 1937, and was the true successor to the popular C-2/C-3 line.

While it was powered by the same Aeronca E-113 two-cylinder engine as the C-3, the Model K Scout was of more conventional appearance, eliminating the C-3's distinctive fuselage "bathtub", replacing the wire-braced wings used by the earlier aircraft with strut-braced wings and providing a fully enclosed cockpit seating two side-by-side.

The aircraft had a fixed tailwheel undercarriage, where the wheels could be replaced with skis for winter operation, while there was also a floatplane version.

The EAA AirVenture Museum in Oshkosh, Wisconsin has an example on display at its Pioneer Airport.
