A vector field on a Kähler manifold is called c-projective if its flow preserves theJ-planar curves. We give a complete local classification of Kähler real 4-dimensional manifolds that admit an essential c-projective vector field. An important technical step is a local description of 4-dimensional c-projectively equivalent metrics of arbitrary signature. As an application of our results we prove the natural analog of the classical Yano–Obata conjecture in the pseudo-Riemannian 4-dimensional case.
