A computer game publisher is a company that publishes computer games developed internally or by separate companies engaged in the development of computer games. As in the case of book publishers, for example, the publisher of computer games is responsible for developing, publishing, promoting, and advertising the game.

Often, the publisher finances the development of the game and pays for the work of the developers. Other functions of the publisher typically include printing the game manual and designing the game box.
