The EKW C-35 was a 1930s Swiss two-seat reconnaissance biplane aircraft built by the Swiss Federal Construction Works (Eidgenoessische Konstruktionswerkstaette, K+W), Thun.

Two aircraft were designed by the Eidgenössische Konstruktions Werkstätte to replace the Fokker C.Ve which the Swiss Air Force were using.

The C-35 was a two-seat biplane with fixed tailwheel landing gear and conventional tail unit.

The aircraft were removed from front-line service in 1943 when replaced by the F&W C-3603 and transferred to night-flying units.
