In geometry, the augmented hexagonal prism is one of the Johnson solids (J_54). As the name suggests, it can be constructed by augmenting a hexagonal prism by attaching a square pyramid (J_1) to one of its equatorial faces. When two or three such pyramids are attached, the result may be a parabiaugmented hexagonal prism (J_55), a metabiaugmented hexagonal prism (J_56), or a triaugmented hexagonal prism (J_57).
