JLA: The Nail is a three-issue comic book mini-series published by DC Comics in 1998 under its Elseworlds imprint. The story, written and drawn by Alan Davis, is set in a parallel universe where Jonathan and Martha Kent's truck experiences a flat tire caused by a nail, which stops them from discovering a Kryptonian spaceship outside Smallville containing the baby Kal-El, negating Superman. It was later followed by a sequel, JLA: Another Nail, a three-issue mini-series published in 2004 which wrapped up several loose ends from the original mini-series, such as the war between the New Gods and the Green Lantern Corps and Oliver Queen's public betrayal of the Justice League.

Alan Davis is an English artist and writer of comic books, known for his work on titles such as Captain Britain, The Uncanny X-Men, ClanDestine, Detective Comics, Excalibur, JLA: The Nail and JLA: Another Nail.
