Anthony Geary (born May 29, 1947 in Coalville, Utah) is an American actor. He has starred on the ABC daytime drama General Hospital as Luke Spencer from 1978 to 1984 and from 1993 to present.

Geary's character began as a "hit man" and later as a rapist who fell in love and subsequently married his victim, Laura Webber (played by Genie Francis). The character became so popular that the writers turned Luke into a protagonist. Luke and Laura's 1981 wedding began what was arguably the greatest love affair in the history of General Hospital, if not daytime television. The early 1980s saw Luke Spencer in a series of nearly improbable storylines seemingly lifted from the pages of a spy novel, which only served to further the character's popularity.

He also portrayed Luke's lookalike cousin Bill Eckert on General Hospital from 1991 to 1993.
