AB  - We study the existence of supersymmetric M5-brane instantons in asymptotically AdS_4 × S^7/Z_k geometries of M-theory, dual to the ABJM theory. The supersymmetric embeddings of these instantons are determined by the M5-brane κ-symmetry, which forces them to localise to the equivariant fixed points in the asymptotically AdS_4 geometry, and wrap $(S^3\times S^3)/\mathbf{Z}_k $. At the quantum level we find that the one-loop partition function of these instantons vanishes, suggesting that the bulk partition function is instead to be expanded in terms of supergravity modes and M2-brane instantons, in line with known results for the S^3 partition function of the dual ABJM theory.
