was a Japanese monthly manga magazine by Kodansha that ran from April 4, 2008 to June 4, 2014. It was issued on the 4th of every month.
As with Shueisha's Jump Square and Shogakukan's Monthly Shōnen Sunday, it was aimed at audiences in their late-teens and early-twenties.
Shōnen Rival was a replacement of Comic BomBom, which ended in December 2007 due to decline in interest. Shōnen Rival followed the same fate and due to decline in interest the final issue was released on June 4, 2014. Kodansha noted that it was reassessing its manga magazine lineup to aim for more growth, and therefore stopped publication on Monthly Shōnen Rival and conducted research for the new magazine that would replace it.
Though most of the series had managed to end by the final issue, all unfinished series were transferred to online platforms such as Manga Box and .
