"Chuck Versus the Cliffhanger" is the fourth season finale of the American NBC action-comedy television series Chuck. Aired on May 16, 2011, it is the season's 24th episode, and the 78th overall episode of the series. The episode was directed by Robert Duncan McNeill and written by series co-creator Chris Fedak, along with Nicholas Wootton. Despite the episode's eponymous cliffhanger ending, supposedly leading into a fifth season, it was anticipated that Chuck would be cancelled after the fourth season for declining viewership, making "Chuck Versus the Cliffhanger" the de facto series finale. However, a fifth and final season was ordered on May 13, 2011.

The fourth season of Chuck was announced on May 13, 2010. Having initially ordered 13 episodes, NBC ordered an additional 11 on October 19, 2010 for a total of 24 episodes. Throughout the season, Chuck faced individual villains: Alexei Volkoff, head of Volkoff Industries, and Volkoff's daughter, Vivian McArthur.
