In geometry, the metabiaugmented dodecahedron is one of the Johnson solids (J60). It can be viewed as a dodecahedron with two pentagonal pyramids attached to two faces that are separated by one face. When pyramids are attached to a dodecahedron in other ways, they may result in an augmented dodecahedron, a parabiaugmented dodecahedron, a triaugmented dodecahedron, or a small stellated dodecahedron.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
