Monthly Shōnen Jump (月刊少年ジャンプ, Gekkan Shōnen Janpu^?) is a now defunct monthly shōnen manga magazine published in Japan by Shueisha from 1970 to 2007 under the Jump line of magazines. It was the sister magazine to Weekly Shōnen Jump.

The Monthly Shōnen Jump magazine started as a spin-off issue of Weekly Jump called Bessatsu Shōnen Jump.

The second spin-off issue was called Monthly Shōnen Jump, which caught on and became its own separate independent manga magazine.

Shōnen manga magazines in Japan in the 1980s focused on bishōjo characters, and Monthly Shōnen Jump stood out due to the many product and toy tie-ins it had during that period and into the 1990s. In 1983 through 1988 a special issue called Hobby's Jump had articles about PC and video games. The games were from early game systems like the Famicom, MSX, and the Mark III. Another spin-off Go!Go! Jump was a collaboration between its sister magazine Weekly Jump and Monthly Jump; it was published in 2005 and was only published once.

On 22 February 2007, Shueisha announced that Monthly Jump would cease publication as of the July issue (on sale June 6, 2007.) Sales had slumped to a third of the magazine's peak, though a new magazine called Jump SQ. took its place on 2 November.

In a letter dated 2 May 2007, Shueisha announced that Claymore takes a month break but it, Gag Manga Biyori, Rosario + Vampire, and Tegami Bachi continued in Weekly Shōnen Jump until the start of the magazine Jump SQ.
