In geometry, the gyrate bidiminished rhombicosidodecahedron is one of the Johnson solids ().
thumb|3D model of a gyrate bidiminished rhombicosidodecahedron
It can be constructed as a rhombicosidodecahedron with two non-opposing pentagonal cupolae () removed and a third is rotated 36 degrees. Related Johnson solids are:
- The diminished rhombicosidodecahedron () where one cupola is removed,
- The parabidiminished rhombicosidodecahedron () where two opposing cupolae are removed,
- The metabidiminished rhombicosidodecahedron () where two non-opposing cupolae are removed,
- And the tridiminished rhombicosidodecahedron () where three cupolae are removed.
