In geometry, the triaugmented dodecahedron is one of the Johnson solids (J_61). It can be seen as a dodecahedron with three pentagonal pyramids (J_2) attached to nonadjacent faces. When pyramids are attached to a dodecahedron in other ways, they may result in an augmented dodecahedron (J_58), a parabiaugmented dodecahedron (J_59), a metabiaugmented dodecahedron (J_60), or even a pentakis dodecahedron if the faces are made to be irregular.
