In this paper we prove the existence of an optimal transport map on non-compact manifolds for a large class of cost functions that includes the case $c(x,y)=d(x,y)$, under the only hypothesis that the source measure is absolutely continuous with respect to the volume measure. In particular, we assume compactness neither of the support of the source measure nor of that of the target measure.
