In geometry, the gyroelongated square cupola is one of the Johnson solids ("J"23). As the name suggests, it can be constructed by gyroelongating a square cupola ("J"4) by attaching an octagonal antiprism to its base. It can also be seen as a gyroelongated square bicupola ("J"45) with one square bicupola removed.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
