The Carley C.12 was a small Dutch single seat sporting monoplane from the 1920s. There were several developments but only small numbers were produced.

Like his earlier Carley S.1, Joop Carley's C.12 was a compact single seat monoplane with a shoulder wing. It differed by being much lighter and all of the several engines fitted were much less powerful than the S.1's 37 kW (50 hp) Gnôme. The wing of the C.12 was a cantilever, thick aerofoil section, low aspect ratio structure built around two wooden box spars, covered with three-ply ahead of the forward spar and fabric behind.

The C.12's fuselage was constructed around three wooden longerons and 3-ply bulkheads, giving it a triangular cross section and entirely plywood covered. The cockpit, within a circular cut-out in the wing, placed the pilot high between the wing spars giving him a good forward view. There were sizeable cut-outs in the wing trailing edge to improve his rearward view downward. The empennage was conventional, the one piece elevator having a cut-out for rudder movement. The fixed, conventional undercarriage was of the divided axle type, the axle enclosed within a wooden aerofoil fairing and hinged on the central lower longeron, with its wheels and extremities on rubber sprung V-form struts to the wing roots at the upper longerons. The small, coil sprung tail skid steered with the rudder.
