(79983) 1999 DF₉, also written as (79983) 1999 DF9, is a cubewano. It travels in a highly eccentric orbit which has a perihelion (closest approach to the Sun) at 39.797 AU and an aphelion (farthest approach from the Sun) at 53.264 AU. It is about 265 km in diameter. It was discovered on February 20, 1999, by Jane X. Luu, Chadwick A. Trujillo and David C. Jewitt.

Due to its small size, it is unlikely to be classified as a dwarf planet.
