Ransom is an internationally co-produced drama television series created by David Vainola and produced by Frank Spotnitz, starring Luke Roberts, that began airing on CBS. Ordered straight-to-series with 13 episodes on June 6, 2016, the series is a co-production between Canada's Global, France's TF1, the United States' CBS, and Germany's RTL, while the latter is airing the series on its sister network VOX. The series premiered on Global and CBS on January 1, 2017.

On May 17, 2017, CBS announced that Ransom was cancelled in the United States. A day later, RTLGroup also reported that they left the project after low ratings in Germany. It was reported on the same day that the other broadcasters behind the series were attempting to fund a second season. In late June, various sources reported that Global and TF1 ordered a second season, to be produced without the former partners. Production was set to start in late July 2017. On October 10, 2017, CBS and Global officially announced that Ransom had been renewed for a 13-episode second season, which premiered on April 7, 2018, on CBS in the United States. On July 16, 2018, CBS and Global announced that the series has been renewed for a 13-episode third season, which premiered on February 16, 2019.

On July 3, 2019, CBS announced that the series had been cancelled after three seasons.

Ransom was the first newly U.S. scripted series that debuted on its Saturday night schedule since The District cancelled in 2004.
