==Trivia==
*This was the shortest season of Supergirl, with 20 episodes, until Season 5 broke it with 19 episodes due to the COVID-19 pandemic that cut that season's 22-episode order short.
*Season 1 marked the only season to air on CBS, to feature Calista Flockhart as a series regular and Greg Berlanti as co-showrunner respectively in addition to being the only season to be filmed in Los Angeles before relocating to Vancouver for the rest of the series.
