4791 Iphidamas (1988 PB1) is a Jupiter Trojan discovered on August 14, 1988 by Shoemaker, C. S. at Palomar.

Photometric observations of this asteroid during 1993 were used to build a light curve showing a rotation period of 9.727 ± 0.011 hours with a brightness variation of 0.49 ± 0.02 magnitude.[2]
