The Keleher JK-1 Lark is a single-seat aerobatic sport aircraft that was designed in the United States in the early 1960s and later marketed for homebuilding. It is a conventional mid-wing strut-braced monoplane with fixed tailwheel undercarriage. The fuselage and empennage are of welded steel tube construction skinned in fabric. The wings are wooden and also covered in fabric. The design was revised in 1963 with the new version designated Lark 1B.
