Rubicon is an American conspiracy thriller television series created by Jason Horwitch and produced by Henry Bromell that was broadcast on the AMC television network in 2010. The series centers on an intelligence analyst working for the American Policy Institute (API) in New York City. The series stars James Badge Dale, Jessie Collins, Lauren Hodges, Miranda Richardson, Dallas Roberts, Christopher Evan Welch, Arliss Howard, and Michael Cristofer.

The original focus of the series was influenced by conspiracy films of the 1970s such as Three Days of the Condor and The Parallax View, in which an innocent character is caught up in, and slowly unravels, a major conspiracy. Creative differences with the network, however, caused Horwitch to leave the series, after which Bromell focused the episodes more on the workers at API, which was changed from a think tank to a private intelligence agency.

Rubicon debuted on AMC on August 1, 2010, as a two-hour, two episode block. With two million viewers, the August 1 premiere set a record as the most watched debut of an AMC original series at that time. However, due to low viewing figures, AMC canceled Rubicon on November 11, 2010, stating that the show had been "an opportunity to tell a rich and compelling story, and we're proud of the series. This was not an easy decision, but we are grateful to have had the opportunity to work with such a phenomenally talented and dedicated team."
