In geometry, the Square gyrobicupola is one of the Johnson solids (J₂₉). Like the square orthobicupola, it can be obtained by joining two square cupolae on their octagonal faces. The difference is a 45 degree difference in the relative orientation of the two halves.

The 92 Johnson solids were named and described by Norman Johnson in 1966.
