Hemo the Magnificent is a one-hour Technicolor made-for-television educational film, released in 1957 by Bell Laboratories and directed by Frank Capra, and first telecast by CBS. It details the workings of the circulatory system.

It is one program in The Bell System Science Series, a series of nine Bell Telephone science specials telecast in prime time on commercial network television from the late 1950s to the mid-1960s. All but one of these specials starred Prof. Frank C. Baxter; the last of them starred Walt Disney.
