Kantai Collection

, subtitled as "Combined Fleet Girls Collection" and abbreviated as KanColle (艦これ, KanKore), is a Japanese free-to-play web browser game developed by Kadokawa Games and published by DMM.com.

The central theme of the game is the representation of World War II warships personified as teenage girls and young adult women with personality characteristics reflecting the history of each ship. Originally, all of these were Japanese, but as the game has developed, ships from other nations have also been added. Gameplay involves all aspects of naval warfare, including not only combat but also maintenance, repair, upgrading, resupply, morale, logistics and mission planning.

The game was launched on April 23, 2013. As of April 2015, the game is available in Japan only and has 3 million registered players. An Android client of the original game was released in 2016. The game has developed into a much larger media franchise; various media including multiple manga series and light novels have been released, in addition to an officially licensed tabletop role-playing game. A PlayStation Vita game was released in February 2016.
