It is shown that if {C,,: n = 1,2,...} is a countable family of Hausdorff k^-topological groups with a common closed subgroup A, then the topological amalgamated free product * G n exists and is a Hausdorff k^-topological group with each G n as a closed subgroup. A consequence is the theorem of La Martin that epimorphisms in the category of k u -topological groups have dense image.
