The Circa Reproductions Nieuports are a family of Canadian 7/8 scale World War I sesquiplane aircraft replicas designed by Graham Lee of Lamont, Alberta for amateur construction from plans sold by Lee's company Circa Reproductions. Leading Edge Air Foils of Peyton, Colorado at one time also made construction kits available. Lee's Nieuports were among the earliest First World War replicas available and paved the way for later companies to produce plans and kits for a great variety of warbirds.

The Nieuport 11, nicknamed the Bébé, is a French World War I single seat sesquiplane fighter aircraft, designed by Gustave Delage. It was the primary aircraft that ended the Fokker Scourge in 1916. The type saw service with several of France's allies, and gave rise to the series of "vee-strut" Nieuport fighters that remained in service into the 1920s.
