Atlas Comics was the 1950s comic-book publishing label that evolved into Marvel Comics. Magazine and paperback novel publisher Martin Goodman, whose business strategy involved having a multitude of corporate entities, used Atlas as the umbrella name for his comic-book division during this time. Atlas evolved out of Goodman's 1940s comic-book division, Timely Comics, and was located on the 14th floor of the Empire State Building. This company is distinct from the 1970s comic-book company, also founded by Goodman, that is known as Atlas/Seaboard Comics.

Marvel Comics is an American comic book publisher and the property of The Walt Disney Company since December 31, 2009, and a subsidiary of Disney Publishing Worldwide since March 2023. Marvel was founded in 1939 by Martin Goodman as Timely Comics, and by 1951 had generally become known as Atlas Comics. The Marvel era began in August 1961 with the launch of The Fantastic Four and other superhero titles created by Stan Lee, Jack Kirby, Steve Ditko, and many others. The Marvel brand, which had been used over the years and decades, was solidified as the company's primary brand.
