In geometry, the gyroelongated pentagonal rotunda is one of the Johnson solids (J₂₅). As the name suggests, it can be constructed by gyroelongating a pentagonal rotunda (J₆) by attaching a decagonal antiprism to its base. It can also be seen as a gyroelongated pentagonal birotunda (J₄₈) with one pentagonal rotunda removed.

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