In six-dimensional geometry, a 'cantellated 5-orthoplex is a convex uniform 5-polytope, being a cantellation of the regular 5-orthoplex.

There are 6 unique cantellation for the 5-orthoplex, including truncations. Some of them are more easily constructed from the dual 5-cube.

The cantellated 5-orthoplex is constructed by a cantellation operation applied to the 5-orthoplex.
