The Northrop N-3PB Nomad was a single-engined American floatplane of the 1940s. Northrop developed the N-3PB as an export model based on the earlier Northrop A-17 design. A total of 24 were purchased by Norway, but were not delivered until after the Fall of Norway during the Second World War. Exiled Norwegian forces used them from 1941, operating from Iceland, for convoy escort, anti-submarine patrols, and training purposes from "Little Norway" in Canada. Within two years of delivery, the design was obsolete for front-line service and the remaining N-3PBs were replaced by larger aircraft in 1943.

Little Norway, officially Flyvåpnenets Treningsleir, was a Norwegian Army Air Service/Royal Norwegian Air Force training camp in southern Ontario during the Second World War.
