The Sikorsky S-40 was a four-engine flying boat built in the 1930s by the Sikorsky Aircraft Corporation for the American airline Pan Am .

The first flight of the S-40 in the service of Pan Am took place on November 19, 1931 under the command of Charles Lindbergh and led from Miami to Barranquilla (Colombia). The wife of then US President Herbert C. Hoover had previously named the aircraft American Clipper . The S-40 thus established the tradition of naming Pan-Am aircraft, which carried Clipper names until the end of the company. The other two S-40s were named Caribbean Clipper and Southern Clipper .

The S-40 was used on scheduled flights to Mexico , Cuba and the Bahamas until it was replaced by its successor, the Sikorsky S-42 .
