The SAI KZ II was a sport aircraft built in Denmark in 1937, produced in three major versions before and after the Second World War. In its original form, designated the Kupé (Danish: "Coupé") it was a low-wing cantilever monoplane of conventional design with fixed tailwheel undercarriage and two seats side-by-side under an enclosed canopy. the fuselage structure was of steel tube, skinned in plywood and fabric, and the wings were wooden with plywood covering and could be folded back along the fuselage for transport and storage.

This was followed by the aerobatic KZ II Sport with a revised fuselage design, placing the two seats in separate open cockpits in tandem, and a dedicated military trainer version along the same lines, the KZ II Træner ("Trainer"). This latter type was first produced in 1946, as a step towards rebuilding Denmark's air force after the war. They remained in service until 1955, when nine examples were sold into private hands.

In 2008, an example of each variant (including the sole extant KZ II Sport) is preserved in the Danmarks Flymuseum.
