We construct and study the electrically charged, rotating black hole solution in heterotic string theory compactified on a (10{minus}{ital D})-dimensional torus. This black hole is characterized by its mass, angular momentum, and a (36{minus}2{ital D})-dimensional electric charge vector. One of the features of this solution is that for {ital D}{gt}5 its extremal limit saturates the Bogomol{close_quote}nyi bound. This is in contrast with the {ital D}=4 case where the rotating black hole solution develops a naked singularity before the Bogomol{close_quote}nyi bound is reached. The extremal black holes can be superposed, and by taking a periodic array in {ital D}{gt}5, one obtains effectively four-dimensional solutions without naked singularities. {copyright} {ital 1996 The American Physical Society.}
