We show that, for fixed k, there is a polynomial-time algorithm that finds a maximum (or maximum-weight) stable set in any graph that belongs to the class of k-colorable P"5-free graphs, or, more generally, to the class of P"5-free graphs that contain no clique of size k+1. This is based on the following structural result: every connected k-colorable P"5-free graph has a vertex whose non-neighbors induce a (k-1)-colorable subgraph.
