Underground is an American period drama television series created by Misha Green and Joe Pokaski about the Underground Railroad in Antebellum Georgia. The show debuted March 9, 2016, on WGN America. On April 25, 2016, WGN renewed the show for a 10-episode second season, that premiered on March 8, 2017. On May 30, 2017, it was announced that WGN had cancelled

the show after two seasons. The cancellation came after the network's parent company Tribune Media was attempting to be purchased by conservative corporation Sinclair Broadcasting Group, which led to speculation that the latter did not approve of the subject matter of the show.

The Oprah Winfrey Network acquired rebroadcast rights for Underground in 2020.
