For a particle described by an irreducible unitary representation of the Poincaré group, for either positive mass or zero mass and discrete helicity, it is shown that the velocity operator can be identified by its transformations under the Poincaré group together with the assumption that it is a Hermitian operator whose different components commute with each other.
