The Bernard 15 C1 or Bernard SIMB AB 15 was a 1920s French single-seat sesquiplane fighter aircraft designed and built by the Société Industrielle des Métaux et du Bois (SIMB).

[1][2] With the structural failure of the earlier Bernard 14 the Bernard 15 was an improved variant with a greater span upper wing.

It was powered by a Hispano-Suiza 12Hb inline piston engine and had a fixed tailskid landing gear.

The performance was not an improvement on the Bernard SIMB AB 14 and only the prototype was built.
