Superman & Lois is an American superhero drama television series developed for The CW by Todd Helbing and Greg Berlanti, based on the DC Comics characters Superman and Lois Lane, created by Jerry Siegel and Joe Shuster. Tyler Hoechlin and Elizabeth Tulloch star as the title characters Clark Kent / Superman and Lois Lane, respectively. Jordan Elsass and Alex Garfin portray the couple's twin sons Jonathan and Jordan Kent, with Michael Bishop replacing the former in the third season. The series also stars Erik Valdez, Inde Navarrette, Wolé Parks, Adam Rayner, Dylan Walsh, Emmanuelle Chriqui, Tayler Buck, Sofia Hasmik, Chad L. Coleman, and Michael Cudlitz.

The series was originally part of the Arrowverse's Earth-Prime in its first season, developed as a spin-off of Supergirl, with Hoechlin and Tulloch respectively reprising their roles from Supergirl and The Flash (and the conclusion of the "Crisis on Infinite Earths" crossover event serving as a backdoor pilot), but as the series went on, following the cancellation of planned crossovers with Supergirl and Batwoman due to the COVID-19 pandemic, showrunner Todd Helbing and Warner Bros. decided to keep the show separate, with the series instead set in its own separate continuity; taking place on a different Earth to the Arrowverse's Earth-Prime, which was confirmed in the second season finale.

Superman & Lois was announced as a pilot in October 2019 and was ordered to series in January 2020. The series aired on The CW for four seasons, from February 23, 2021 to December 2, 2024.
