I Wanna Be the Boshy is a free 2D platform game created by Danish game developer Jesper "Solgryn" Erlandsen.

The name is a reference to the platformer I Wanna Be the Guy, which I Wanna Be the Boshy is a fangame of, with "Boshy" being a tribute to game streamer BoshyTime whom Erlandsen liked to watch. Many of the game's elements are tributes/parodies of popular video games. Good examples of this are three of the bosses being MarioRyu, and Sonic.

The game is popular in the speedrunning community, and has been featured at multiple Games Done Quick events.
