Tomb Raider, also known as Lara Croft: Tomb Raider from 2001 to 2008, is a media franchise that originated with an action-adventure video game series created by British gaming company Core Design. Formerly owned by Eidos Interactive, then by Square Enix Europe after Square Enix's acquisition of Eidos in 2009, the franchise focuses on the fictional British archaeologist Lara Croft, who travels around the world searching for lost artefacts and infiltrating dangerous tombs and ruins. Gameplay generally focuses on exploration of environments, solving puzzles, navigating hostile environments filled with traps, and fighting enemies. Additional media has been developed for the franchise in the form of film adaptations, comics and novels. On January 27, 2023, The Hollywood Reporter exclusively reported that Amazon was in the works with Phoebe Waller-Bridge reportedly set to write a TV Show adaptation of the video game franchise. It was also reported this would involve a tie-in video game and movie in an interconnected universe, likened to the Marvel Cinematic Universe.

Development of the original Tomb Raider game began in 1994; it was released two years later. Its critical and commercial success prompted Core Design to develop a new game annually for the next four years, which put a strain on staff. The sixth game, The Angel of Darkness, faced difficulties during development and was considered a failure at release. This prompted Eidos to switch development duties to Crystal Dynamics, which has been the series' primary developer since. Other developers have contributed to spin-off titles and ports of mainline entries.

Tomb Raider games have sold over 95 million copies worldwide by 2022. while the entire franchise generated close to $1.2 billion in revenue by 2002. The series has generally been met with critical acclaim, and Lara Croft has become one of the most recognisable video game protagonists, winning accolades and earning places on the Walk of Game and Guinness World Records.
