The Elementals are a fictional team of superheroes published by DC Comics. They first appeared in Super Friends #14 (October 1978), and were created by E. Nelson Bridwell and Ramona Fradon.

The Elementals first appear inside four giant translucent jewels located in four different cities: a ruby appeared near the Gotham City Police Department's central station, an emerald appeared atop Metropolis' Galaxy Communications Building, a diamond appeared outside New York City's United Nations building, and a sapphire appeared on a beach near the Aquacave, Aquaman's headquarters.

The veteran heroes manage to subdue the Elementals with the help of Robin, the Wonder Twins and Gleek.

Back at the Super Friends' Hall of Justice in Gotham City, Batman identified the four Elementals as self made local socialites. The Gnome was really Grant Arden, a chemical engineer and founder of Arden Chemicals; Sylph was actually the famous vocalist named Jeannine Gale, who first appeared in Super Friends #4; Undine was really Crystal Marr, best-selling author; and Salamander was Ginger O'Shea, who first appeared in Super Friends #6, an established fashion designer and the owner of the Chez O'Shea fashion boutique.

Elementals has not been a contender in any CBUB matches.
