John McCrea (born 1966 in Belfast, Northern Ireland) is a comics artist best known for his collaborations with writer Garth Ennis. He is the older brother of Jasper McCrea.
He and Fred Collier founded Belfast's first comic shop, Dark Horizons, in the back of Terri Hooley's record shop Good Vibes in about 1985.
His earliest work was influenced by John Byrne and Alan Davis. In 1988, after a few years of drawing television and toy tie-ins, he illustrated Ennis's debut, the political series Troubled Souls, in Crisis, in a realistic style, using acrylic paints and mixed media, but its sequel, the farce For a Few Troubles More, showed him moving a more cartoony direction, a trend which continued with his occasional series Carla Allison in Deadline and Negative Burn.
He broke into American comics in 1993, drawing Ennis's run on DC Comics' The Demon, followed by its spin-off, Hitman, from 1996 to 2001, on which McCrea developed a versatile drawing style equally at home with goofy humour, action, and subtle characterisation. Hitman issue 34 won the Eisner Award for best single issue in 1999. His wilder, more exaggerated cartooning found an outlet with Dicks, a miniseries spinning off from For a Few Troubles More into more outrageous dialect, sexual and toilet humour, published by Caliber Comics in 1997, with a sequel, Dicks II, from Avatar Press in 2002.
Since Hitman finished he has drawn a variety of characters for DC, Marvel, Dark Horse Comics, 2000AD and others. In 2005 he co-created The Atheist with writer Phil Hester for Image Comics. He has contributed art to Garth Ennis' series The Boys, and drawn original superhero strips for Marvel UK's Spectacular Spider-Man and Marvel Heroes, and is working on "Warpaint", with writer Phil Hester, for the forthcoming UK-based anthology Strip Magazine.
