Bill Nye Saves the World is an American television show streaming on Netflix hosted and created by Bill Nye. It is both a sequel and a revival of sorts of Bill Nye the Science Guy, which is also created by Nye. The show's byline was, "Emmy-winning host Bill Nye brings experts and famous guests to his lab for a talk show exploring scientific issues that touch our lives", with the series' focus placed on science and its relationship with politics, pop culture, and society. Unlike Nye's previous show Bill Nye the Science Guy (which is revived in this show) which was intended for children, Bill Nye Saves the World is intended for adults (especially those adults who watched Bill Nye the Science Guy when they were children during its original run in the 1990s). As such, some episodes have Nye discuss topics that would be considered inappropriate to mention to minors.

Though the show was hosted by Nye, five correspondents assist in the presentation of the show. These include fashion model Karlie Kloss, science YouTuber and educator Derek Muller, comedian Nazeem Hussain, comedian and writer Joanna Hausmann, and the TV host and producer Emily Calandrelli. The show's theme song was produced by Tyler, the Creator. The thirteen-episode first season premiered on April 21, 2017. A six-episode second season premiered on December 29, 2017, and a six-episode third season was released on May 11, 2018. Reception to the series has been mixed, with the first season being reviewed more positively by critics than audiences.
