Alpha Lupi (afgekort as α Lup) is die helderste ster in die suidelike sterrebeeld Wolf (Lupus). Dit het ’n skynbare magnitude van 2,3,[3] wat beteken dit is met die blote oog sigbaar. Volgens parallaksmetings[11] is die ster sowat 460 ligjare van die Son af.[2] Dit is die naaste ster wat amper as ’n supernova gaan ontplof.[12]
