Dengeki G's Magazine

is a Japanese magazine published by ASCII Media Works and sold monthly on the thirtieth that primarily focuses on the bishōjo game genre, including related media such as anime and serialized manga and light novels. The "G's" in the title stands for "Gals" and "Games". The magazine is known for hosting reader participation games whose outcome is directly influenced by the people who read the magazine; such games include Sister Princess, and Strawberry Panic!.

A special edition spin-off version called Dengeki G's Festival! is published in irregular intervals and each issue focuses on a specific bishōjo game. Four other special edition versions under the Festival! name are Dengeki G's Festival! Comic, Dengeki G's Festival! Deluxe, Dengeki G's Festival! Anime, and Dengeki Festival! Heaven. Dengeki G's Magazine's sister magazine is Dengeki Girl's Style, which publishes information on otome games, targeted towards females.

Reader participation games
Dengeki G's Magazine often hosts reader participation games whose outcome is directly influenced by the people who read the magazine. The length of these games vary to which the poular ones can go on for years, while others end in less than a year. How long a game lasts is decided on how popular the game is among the readers and how many readers participate. At least one game has been running in the magazine since the first issue except during the time between the December 1998 and February 1999 issues when Ojōsama Express ended and Sister Princess began, and again with the November 2005 issue between when Futakoi ended and 2/3 Ai no Kyōkaisen began.
