In geometry, the triangular orthobicupola is one of the Johnson solids (J₂₇). It has a superficial resemblance to the cuboctahedron, which would be known as the triangular gyrobicupola in the nomenclature of Johnson solids. It has equal number of squares and triangles at each vertex, however, it is not vertex-regular, as at some of the vertices the arrangement is triangle-square-triangle-square while at others it is triangle-triangle-square-square.
