Queen's Gate (Japanese: クイーンズゲイト, Hepburn: Kuīnzu Geito) is a series of visual combat books published by Hobby Japan.

The supplement to the Queen's Blade series, it features licensed female characters from other games and works, including those from Hobby Japan.

In the original game, the general story comes from Alice's bio: she is a treasure hunter who one day discovers the "Queen's Gate", which unleashes a battle across space-time.

A novel adaptation of Queen's Gate was written by Eiji Okita and Eiichi Shitara with illustrations by Niθ and Kanko Nakamura.

Like the first game, Queen's Gate: Spiral Chaos also features an original storyline with game-exclusive characters.
