In geometry, the Parabidiminished rhombicosidodecahedron is one of the Johnson solids (J80). It can be constructed as a rhombicosidodecahedron with two opposing pentagonal cupola removed. Related Johnson solids are the diminished rhombicosidodecahedron (J76) where one cupola is removed, the metabidiminished rhombicosidodecahedron (J81) where two non-opposing cupolae are removed and the tridiminished rhombicosidodecahedron (J83) where three cupolae are removed.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
