Paul Daniel Frehley (born April 27, 1951) aka Ace Frehley, is best known as the lead guitarist for the rock band KISS.

Frehley joined Paul Stanley, Gene Simmons and Peter Criss in the early 1970s as lead guitarist for their yet unnamed band. Wicked Lester was the name of Paul and Gene's band prior to hooking up with Ace and Peter. They recorded an album, but as of 2002, it has never been released. KISS released their first self-titled debut in February of 1974. Ace Frehley along with the three other KISS members, recorded solo albums in 1978. He had a #13 hit with "New York Groove."

Frehley left Kiss in 1982 and formed a solo act, Frehley's Comet.

Frehley returned to KISS in 1995 for several reunion tours. He participated in the "Farewell Tour" in 2000 but once Gene and Paul decided to continue touring beyond the planned "Farewell," Ace once again left the band.

Frehley is starring alongside actors from The Sopranos in a DVD to be released in March 2005 called Remedy.
