Cyberpunk 2077 is a 2020 action role-playing game developed by the Polish studio CD Projekt Red, and published by CD Projekt, and based on Mike Pondsmith's Cyberpunk tabletop game series. The plot is set in the fictional metropolis of Night City, California, within the dystopian Cyberpunk universe.

The player assumes the role of V (voiced by Gavin Drea or Cherami Leigh), a mercenary who accidentally gets imbued with a cybernetic "bio-chip" containing an engram of legendary rockstar and terrorist Johnny Silverhand (voiced by Keanu Reeves). As Johnny’s behaviour and memories begin overwriting V’s own, the two must work together to separate from each other and save V's life.

Cyberpunk 2077 received praise from critics for its narrative, setting, and graphics. However, some of its gameplay elements received mixed responses while its themes and representation of transgender characters received some criticism.

It was also widely criticized for bugs and glitches, particularly on the PlayStation 4 and Xbox One versions. Sony removed it from the PlayStation Store from December 2020 to June 2021 while CD Projekt rectified some of the issues. CD Projekt became subject to investigations and class-action lawsuits for their perceived attempts at downplaying the severity of the technical problems before release; these were ultimately cleared with a settlement of US$1.85 million.

Its total cost to develop and market (including updates and DLC) is reportedly over $436 million, making it one of the most expensive video games to develop. By October 2023, the game had sold over 25 million units. A sequel, internally codenamed "Project Orion", was announced in October 2022. An expansion, Phantom Liberty, was released for PlayStation 5, Microsoft Windows, and Xbox Series X/S on 26 September 2023.
