The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if G can be realized as both the fundamental group of a closed 3-manifold and of a compact K”ahler manifold, then G must be finite, and thus belongs to the well-known list of finite subgroups of O(4), acting freely on S^3.
