In geometry, the elongated pentagonal bipyramid is one of the Johnson solids (J16). As the name suggests, it can be constructed by elongating a pentagonal bipyramid (J13) by inserting a pentagonal prism between its congruent halves.

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

Dual polyhedron

The dual of the elongated square bipyramid is a pentagonal bifrustum.
