In geometry, the Elongated pentagonal gyrobirotunda is one of the Johnson solids (J43). It is a similar construction to another Johnson solid, the Elongated pentagonal orthobirotunda. The difference is a twist of 36 degrees between the two pentagonal rotundae.

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