is a Japanese monthly shonen manga magazine. Published by Shueisha, the magazine premiered on November 2, 2007 as a replacement for Monthly Shonen Jump, another manga anthology that Shueisha discontinued in June of that year. The magazine is a part of the Jump line of magazines. The manga titles serialized in the magazine are also published in tankobon volumes under the Jump Comics label. The manga series within the magazine target young male readers and tend to be set in a fantasy setting with a large amount of action scenes. Like all monthly shonen manga magazines, Jump Square is aimed at ages 16 to 21. The current (2015) editor-in-chief is Kôsuke Yahagi.
