The '''Fokker B.II''' was a prototype sesquiplane shipboard reconnaissance [[Engineering:Flying boat|flying boat]] built in the Netherlands in 1923.

==Development==
It was a conventional flying boat with a [[Chemistry:Duralumin|duralumin]] hull and sesquiplane wings braced with N-struts. The [[Engineering:Tractor configuration|tractor configuration]] engine was mounted on the leading edge of the upper wing driving a four-bladed propeller. Open cockpits were provided for the crew under the upper wing and in a dorsal position amidships.

The Royal Dutch Navy tested the prototype, but no production orders followed.
