Alpha Pictoris (afgekort as α Pic) is die helderste ster in die suidelike sterrebeeld Skilder (Pictor). Dit het ’n skynbare magnitude van 3,27,[3] wat dit geredelik sigbaar met die blote oog maak. Volgens parallaksmetings is dit omtrent 97 ligjare van die Son af.[2] Alpha Pictoris is uitsonderlik in die sin dat dit die suidpoolster van die planeet Mercurius is.[12]
