The **truncated triangular prism** is a polyhedron formed by truncating the vertices of the triangular prism. It has 6 isosceles triangles, 3 rectangular-symmetric octagons and 2 ditrigons as faces.

The canonical variant with midradius 1 has four edge lengths: one of length , one of length , one of length and the other of length . It has regular hexagons in place of ditrigons.

A variant of the truncated triangular prism with (A_{2}×A_{1})+ symmetry occurs as the single cell-type of the tetraswirlic hexadecachoron.
