Superman/Shazam!: The Return of Black Adam is a 2010 direct-to-video animated superhero short film co-produced and directed by Joaquim Dos Santos and written by Michael Jelenic, about the DC Comics characters Superman and Captain Marvel / Shazam cooperating to battle the powerful villain Black Adam. George Newbern and Jerry O'Connell reprised their roles from the DC animated series Justice League Unlimited as the two leads.

Released on November 9, 2010 as the main feature on the compilation DVD DC Showcase Original Shorts Collection, Superman/Shazam!: The Return of Black Adam was the fourth (and to date, longest) of the DC Showcase series, which were also included in extended versions. This also marked James Garner's last performance before his retirement the same year and his death on July 19, 2014.
