Three Dimensional E.C. Classics was a quarterly comic book anthology series published by EC Comics in 1954. It began publication with its Spring 1954 issue and ceased with its March 1954 issue, producing a total of two issues. The stories it contained were classics in that they were recyclings of stories that had already appeared in earlier EC comic books. They were three-dimensional because they were presented in Anaglyph 3-D. Two 3-D viewers were included with each issue.
