Black Lightning is an American superhero drama television series, developed by Salim Akil, that premiered on The CW on January 16, 2018, and concluded on May 24, 2021. It is based on the character of the same name, created by Jenny Blake Isabella with Trevor Von Eeden, featured in publications of DC Comics. Cress Williams stars as the titular character alongside China Anne McClain, Nafessa Williams, Christine Adams, Marvin "Krondon" Jones III, Damon Gupton, James Remar, Jordan Calloway, and Chantal Thuy. The series sees the retired Black Lightning return to his life as a superhero and follows the effects of his vigilante activity on his professional and family life.

Originally in development at Fox, the project was given a pilot production commitment in September 2016. In February 2017, Fox passed on the project and The CW subsequently picked it up with an order for a new pilot script. The CW officially ordered Black Lightning to series in May 2017. The first season premiered on January 16, 2018, and ran for 13 episodes. In April 2018, The CW renewed the series for a second season, which premiered on October 9, 2018, and ran for 16 episodes.

The show's third season, which premiered on October 7, 2019, featured the series' first tie-ins with the network's other DC Comics television series, known collectively as the Arrowverse, leading into Williams' appearance as Black Lightning in their "Crisis on Infinite Earths" crossover event, which resulted in the series' setting merging with that of the other Arrowverse shows. The fourth and final season premiered on February 8, 2021, ending on May 24, 2021.
