Phil Jimenez (born July 12, 1970, in Los Angeles, California) is an American comic book artist and writer, known for his work as writer/artist on Wonder Woman from 2000 to 2003, as one of the five pencilers of the 2005-2006 miniseries Infinite Crisis, and his collaborations with writer Grant Morrison on New X-Men and The Invisibles.

Phil Jimenez was born and raised in Los Angeles and later Orange County, California. He moved to New York City to attend college at the School of Visual Arts, where he majored in cartooning. He graduated with a Bachelor of Fine Arts degree in 1991.

After graduating from SVA, Jimenez was hired by DC Comics Creative Director Neal Pozner at age 21, with his first published work illustrating four pages in the 1991 miniseries War of the Gods. Pozner was HIV-positive when he and Jimenez started dating, and was hesitant about dating someone younger and HIV-negative. Nonetheless, Jimenez became both Pozner's partner and caretaker, saying:

Following Neal Pozner's death in 1994, Jimenez wrote and illustrated the 1996 DC miniseries, Tempest, based on a character from Pozner's late-80s Aquaman series. In the last issue, Jimenez dedicated the miniseries to Pozner, and wrote an editorial page in which he came out publicly for the first time. "It got over 150 letters," he says, "including the classic letter from the kid in Iowa: 'I didn't know there was anyone else like me.' That's what counts. It meant a lot to people."
