Equinox (Terrance Sorenson) is a fictional character, a supervillain appearing in American comic books published by Marvel Comics.

Equinox, the Thermodynamic Man, first appeared in Marvel Team-Up vol. 1 #23 (July 1974), and was created by Len Wein and Gil Kane. He also appeared in Giant-Size Spider-Man #1, also in July 1974, and a two-part story in Marvel Team-Up vol. 1 #59-60 (July–August 1977).

After a nearly 20-year hiatus, the character appeared sporadically, appearing in Marvel Comics Presents #147 (February 1994), Code of Honor #1 (January 1997), Spider-Man Unlimited #12 vol. 2 (January 2006), and Heroes for Hire vol. 2 #1 (October 2006). A Skrull impersonator of Equinox appeared in Avengers: The Initiative #12 (June 2008) and #18.

Equinox received an entry in the All-New Official Handbook of the Marvel Universe A-Z #4 (2006).

Equinox is an African-American youth who gained superhuman powers due to accidental exposure to his father's malfunctioning equipment after a lab accident. (His mother is Margay Sorenson, head of natural sciences at Bard College.)

Equinox's powers were similar to the combined abilities of superheroes the Human Torch and Iceman, with whom he first battled, as well as enhanced strength and durability. He engages in conflict with the superheroes Spider-Man, Yellowjacket, and the Wasp, during which his origin was revealed, the three heroes managing to apparently cure him using technology conceived by his mother and constructed in the Baxter Building while the Fantastic Four were away.
