In geometry, the gyroelongated pentagonal rotunda is one of the Johnson solids ("J"25). As the name suggests, it can be constructed by gyroelongating a pentagonal rotunda ("J"6) by attaching a decagonal antiprism to its base. It can also be seen as a gyroelongated pentagonal birotunda ("J"48) with one pentagonal rotunda removed.
The 92 Johnson solids were named and described by Norman Johnson in 1966.
