In geometry, the gyroelongated triangular cupola is one of the Johnson solids ("J"22). As the name suggests, it can be constructed by gyroelongating a triangular cupola ("J"3) by attaching a hexagonal antiprism to its base. It can also be seen as a gyroelongated triangular bicupola ("J"44) with one triangular cupola removed.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
