A Warfield group is a direct summand of a simply presented abelian group. In this paper, the Pontrjagin dual groups of Warfield groups are described, both for the \(p\)-local and the general case. A variety of characterizations of these dual groups is obtained. In addition, numerical invariants are given that distinguish between two such groups which are not topologically isomorphic.
