The Fisher FP-404 is a Canadian single-seat, conventional landing gear, single-engined biplane kit aircraft designed for construction by amateur builders.

Fisher Flying Products was originally based in Edgeley, North Dakota, USA but the company is now located in Woodbridge, Ontario, Canada.

The 404's standard empty weight is 275 lb (125 kg) when equipped with a two-stroke 50 hp (37 kW) Rotax 503 engine, putting it into the US experimental-amateur-built category, although it qualifies as an ultralight in other countries, such as Canada.

The design goal was to provide a nostalgic aircraft reminiscent of the biplanes of the 1930s, as the company explains "The FP-404 represents a reborn era in airborne adventure.
