In geometry, the augmented hexagonal prism is one of the Johnson solids (J₅₄). As the name suggests, it can be constructed by augmenting a hexagonal prism by attaching a square pyramid (J₁) to one of its equatorial faces.

A Johnson solid is one of 92 strictly convex polyhedra that have regular faces but are not uniform (that is, they are not Platonic solids, Archimedean solids, prisms or antiprisms). They were named by Norman Johnson, who first listed these polyhedra in 1966.^[1]
