The Fokker C.XI-W was a reconnaissance seaplane designed to operate from warships that was produced in the Netherlands in the mid-1930s. It was the result of a Royal Netherlands Navy specification of 1935 requesting such an aircraft. Fokker's response was a conventional single-bay biplane with staggered wings of unequal span braced by N-struts. The pilot and observer sat in tandem, open cockpits, and the undercarriage consisted of twin pontoons. The wings were of wooden construction with plywood and fabric covering, and the fuselage was of steel tube, also covered with fabric.
