Super Mario 3D All-Stars is a 2020 compilation of platform games for the Nintendo Switch. It commemorates the 35th anniversary of Nintendo's Super Mario franchise, with high-definition ports of Super Mario 64 (1996), Super Mario Sunshine (2002), and Super Mario Galaxy (2007).

The Super Mario Bros. 35th Anniversary was a celebration of the Super Mario video game series created by Shigeru Miyamoto. The series began with the release of Super Mario Bros. on September 13, 1985, and has since spanned over twenty games appearing on every major Nintendo video game console. Through a series of leaks initially reported by Video Games Chronicle in March 2020, plans revealed that Nintendo originally planned to celebrate the anniversary earlier in 2020; however, due to the COVID-19 pandemic, the anniversary was postponed to September that same year. The anniversary was announced in a Nintendo Direct on September 3, 2020, and ran until March 31, 2021.
