Chrono Break is a cancelled third mainline entry in the Chrono series of video games by Square. While never officially announced by the company, commentary from Chrono series developers Masato Kato, Hironobu Sakaguchi, and Takashi Tokita have confirmed early plans for the game, alongside a number of trademarks filed in the game's name. However, the game would ultimately go unproduced, with many members of the internal development team either moving on to Final Fantasy XI or leaving the company in favor of freelance work. The game elicited much commentary from the company and the video game press in the following years, though as of 2021, all trademarks had expired, with no announced plans to work on the game.
