The Werdau–Mehltheuer railway is a branch line in the German states of Saxony and Thuringia, originally built and operated by the Royal Saxon State Railways (Königlich Sächsische Staatseisenbahnen). The section from Werdau to Weida via Wünschendorf is now closed. The section between Weida and Mehltheuer is part of the Gera–Hof link.
