The elongated tetrahedral-octahedral honeycomb, or etoh, also known as the elongated alternated cubic honeycomb, is a convex uniform honeycomb. 3 octahedra, 4 tetrahedra, and 6 triangular prisms join at each vertex of this honeycomb.

It can be formed by inserting layers of triangular prisms between layers of cells of the tetrahedral-octahedral honeycomb. It shares its vertex figure with the gyroelongated tetrahedral-octahedral honeycomb.
