Neal Adams (born June 6, 1941) is a comic book artist best known for his superhero stories which have a very naturalistic style of illustration.

His period of greatest fame and influence in the medium was in the late 1960s and 1970s with the characters Deadman, Green Arrow, Green Lantern and, most famously, Batman. His best known collaborator is writer Dennis O'Neil who created noteworthy stories that reestablished Batman's dark brooding nature and experimented with social commentary in the Green Lantern title.

During the 1970s Adams mostly did illustration for paperback publishers and some film work but with the Independent Comic Publishing Boom of the early 1980s he did work for Pacific Comics and other publishers. Adams later started his own company, Continuity Press , which featured artwork by various artists who predominantly imitated their boss's illustration style.

In recent years DC Comics published deluxe hardcover collections of Adams works including:

• Green Lantern Green Arrow Collection - 2000 US$75.00 ISBN 1563896397
• Deadman Collection - 342 pages 2001 US$75.00 ISBN 1563898497
