Robert Bernard Cornelis Noorduyn (April 6, 1893 – February 22, 1959) was a Dutch-born American aircraft designer and manufacturer.

Noorduyn was born in Nijmegen, Netherlands, to a Dutch father, Bernardus Noorduijn (1860–1910), and an English mother, Harriet Ellen Churchill.

He was also heavily involved in the design of an improved version of the Bellanca Pacemaker, another favourite of bush flyers in Canada.

[3] Noorduyn's bush plane design revolved around a few basic criteria: it should be an aircraft with which a Canadian operator utilizing existing talents, equipment, and facilities could make money; it should be a high-wing monoplane to facilitate loading and unloading of passengers and cargo at seaplane docks and airports; and it should be an all-around superior aircraft to those currently in use in Canada.

The final design layout looked much like one of the Fokker models with all-welded steel tubing fuselage structure and wood stringers were applied to it for attachment of a fabric skin.
