In geometry, the elongated triangular bipyramid is one of the Johnson solids (J14). As the name suggests, it can be constructed by elongating a triangular bipyramid (J12) by inserting a triangular prism between its congruent halves.

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