The REP Type K was a two-seat sport aircraft designed and produced in France by Robert Esnault-Pelterie, beginning in 1913. A Type K was exhibited at the 1913 Paris Aero Show. Unlike his first designs, it was of conventional configuration, one of a family of related aircraft he produced around this time. A military version was produced in 1914. This example, construction number 27, is preserved with the Musée de l'Air et de l'Espace at Le Bourget.
