On August 26, 2013, Entertainment Weekly announced that Syfy was developing a 12 Monkeys television series based on the film. Production began in November 2013. The pilot was written by Terry Matalas and Travis Fickett, who had previously written for the series Terra Nova. Due to the series being labeled as "cast contingent", the series did not move forward until the roles of Cole and Goines were cast.

On March 12, 2015, the series was renewed for a second season that began airing in April 2016. On June 29, 2016, the series was renewed for a 10-episode third season, set to premiere in 2017. The third season aired over three consecutive nights, from May 19 to May 21, 2017. A fourth and final season was announced on March 16, 2017. The eleven-episode fourth season ran from June 15 to July 6, 2018.
