An operator S is a local intertwiner of operators A and B at vector e if SAe = BSe. We characterize the spaces of all local intertwiners I(A, B; e) that are reflexive (hyperreflexive). We show that in all interesting cases the reflexivity (hyperreflexivity) of I(A, B; e) depends only on B and is independent of A and e. This has consequences concerning the reflexivity of the space of intertwiners I(A, B) and of the commutant of an operator.
