The 10x10x10 cube (normally referred to as the 10x10x10 or 10x10) is a twisty puzzle in the shape of a cube that is cut 9 times along each of three axes. Two true, flat, commercially available 10x10 cubes, the YuXin HuangLong and ShengShou cubes, have been released.

The cube is the subject of an inside meme "whoa, is that a 10x10?" within the cubing community, as popularised by YouTube cuber ColorfulPockets.
