In geometry, the gyroelongated triangular cupola is one of the Johnson solids (J22). As the name suggests, it can be constructed by gyroelongating a triangular cupola (J3) by attaching a hexagonal antiprism to its base. It can also be seen as a gyroelongated triangular bicupola (J44) with one triangular cupola removed.

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