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. However, all new artwork was done for these books, rather than applying the 3-D process to the original illustrations from the first presentations of the stories. They were three-dimensional because they were presented in Anaglyph 3-D. Two 3-D viewers were included with each issue.
