We identify a group of similar to 20 comoving, mostly southern hemisphere, similar to 200 Myr old stars near Earth. Of the stars likely to be members of this Carina-Near moving group, in either its nucleus (similar to 30 pc from Earth) or its surrounding stream, all but three are plausible members of a multiple star system. The nucleus is ( coincidentally) located quite close to the nucleus of the AB Doradus moving group notwithstanding that the two groups have substantially different ages and Galactic space motions, UVW.
