The Infinite Game is a 2019 book by Simon Sinek, applying ideas from James P. Carse's similarly titled book, Finite and Infinite Games to topics of business and leadership.

The book is based on Carse's distinction between two types of games: finite games and infinite games. As Sinek explains, finite games (e.g. chess and football) are played with the goal of getting to the end of the game and winning, while following static rules. Every game has a beginning, middle, and end, and a final winner is distinctly recognizable. In contrast, infinite games (e.g. business and politics) are played for the purpose of continuing play rather than to win. Sinek claims that leaders who embrace an infinite mindset, aligned with infinite play, will build stronger, more innovative, inspiring, resilient organizations, though these benefits may accrue over larger timescales than benefits associated with a finite mindset.
