We provide a three-dimensional shape model of the near-Earth asteroid (66391) 1999 KW4 based on radar images obtained from Arecibo and Goldstone as reported by Ostro et al. (2006).  The radar data were taken in 2001 and show that 1999 KW4 is a binary system.  Three-dimensional shape models of the primary (Alpha) and secondary (Beta) bodies were created by Ostro et al. (2006).  The models provide a good match to the image resolution of 38 m.
