Elastic neutron scattering measurements performed on single crystal UNi{sub 2}Al{sub 3} show this heavy fermion superconductor to display long-range incommensurate (IC) magnetic order below T{sub N}=5.2K. The ordering wavevector is (1/2 {+-} {tau},0,1/2) with {tau}=0.110{+-}0.003, and the size of the maximum ordered moment is 0.24{+-}0.1{mu}{sub B}/U.
