| Abstract: | We characterize regular boundary points for p-harmonic functions using weak barriers. We use this to obtain some consequences on boundary regularity. The results also
hold for  -harmonic functions under the usual assumptions on  , and for Cheeger p-harmonic functions in metric spaces.
