9917 Keynes is a main belt asteroid. It orbits the Sun once every 3.65 years.[1]

Discovered on June 26, 1979 by Carlos Torres at the Cerro El Roble Astronomical Station, it was given the provisional designation "1979 MK"[2] and later named Keynes after British economist John Maynard Keynes (1883–1946).[1] This choice of name may have been inspired by the provisional designation (MK).
