Bessatsu Shōnen Sunday(別冊少年サンデーBessatsu Shōnen Sandē) was a monthly manga magazine published by Shogakukan in Japan from Spring 1960 until March 1974. It was initially published quarterly, but switched to a monthly release beginning in December 1964. Due to sluggish sales and the paper shortage caused by the 1973 oil crisis, the magazine's last issue was the March 1974 issue.
