In geometry, the metabiaugmented dodecahedron is one of the Johnson solids (J_60). It can be viewed as a dodecahedron with two pentagonal pyramids (J_2) attached to two faces that are separated by one face. (The two faces are not opposite, but not adjacent either.) 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 triaugmented dodecahedron (J_61), or even a pentakis dodecahedron if the faces are made to be irregular.
