Man vs. Wild, also called Born Survivor: Bear Grylls, Ultimate Survival, Survival Game, or colloquially as simply Bear Grylls in the United Kingdom, is a survival television series hosted by Bear Grylls on the Discovery Channel. In the United Kingdom, the series was originally shown on Channel 4, but the show's later seasons were broadcast on Discovery Channel U.K. The series was produced by British television production company Diverse Bristol. The show was premiered on November 10, 2006, after airing a pilot episode titled "The Rockies" on March 10, 2006.

Grylls also said he has been approached about doing a Man vs. Wild urban disaster 3D feature film, which he said he would "really like to do". He signed on to showcase urban survival techniques in a Discovery show called Worst-Case Scenario, which premiered on May 5, 2010, on the network.

The Discovery Channel terminated its legal relationship with Grylls in 2012 due to contract disputes, effectively canceling the series. In April 2019, Netflix brought Grylls back to the wilderness in the interactive series You vs. Wild, which includes eight episodes running approximately 20 minutes each.
