In [[geometry]], the '''gyroelongated triangular cupola''' is one of the [[Johnson solid]]s  (''J''<sub>22</sub>). It can be constructed by attaching a [[hexagonal antiprism]] to the base of a [[triangular cupola]] (''J''<sub>3</sub>).  This is called "gyroelongation", which means that an [[antiprism]] is joined to the base of a solid, or between the bases of more than one solid.

The gyroelongated triangular cupola can also be seen as a [[gyroelongated triangular bicupola]] (''J''<sub>44</sub>) with one triangular cupola removed. Like all [[cupola]]e, the [[base (geometry)|base]] [[polygon]] has twice as many sides as the top (in this case, the bottom polygon is a [[hexagon]] because the top is a [[triangle]]).
