Atlas/Seaboard Comics is a line of comic books published by the American company Seaboard Periodicals in the 1970s. Though the line was published under the brand Atlas Comics, comic book historians and collectors refer to it as Atlas/Seaboard Comics to differentiate it from the 1950s Atlas Comics, a predecessor of Marvel Comics. Seaboard was located on Fifth Avenue in Manhattan, New York City.

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.
