  We demonstrate that crystal defects can act as a probe of intrinsic
non-Hermitian topology. In particular, in point-gapped systems with periodic
boundary conditions, a pair of dislocations may induce a non-Hermitian skin
effect, where an extensive number of Hamiltonian eigenstates localize at only
one of the two dislocations. An example of such a phase are two-dimensional
systems exhibiting weak non-Hermitian topology, which are adiabatically related
to a decoupled stack of Hatano-Nelson chains. Moreover, we show that strong
two-dimensional point-gap topology may also result in a dislocation response,
even when there is no skin effect present with open boundary conditions. For
both cases, we directly relate their bulk topology to a stable dislocation
non-Hermitian skin effect. Finally, and in stark contrast to the Hermitian
case, we find that gapless non-Hermitian systems hosting bulk exceptional
points also give rise to a well-localized dislocation response.
