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.
