The edge physics of graphene based systems is well known to be highlysensitive to the atomic structure at the boundary, with localized zero modeedge states found only on the zigzag type termination of the lattice. Here wedemonstrate that the graphene twist bilayer supports an additional class ofedge states, that (i) are found for all edge geometries and thus are robustagainst edge roughness, (ii) occur at energies coinciding with twist inducedvan Hove singularities in the bulk and (iii) possess an electron densitystrongly modulated by the moir\'e lattice. Interestingly, these "moir\'e edgestates" exist only for certain lattice commensurations and thus the edgephysics of the twist bilayer is, in dramatic contrast to that of the bulk, notuniquely determined by the twist angle.
