was a German six-coupled tender locomotive built for the Royal Saxon State Railways (Königlich Sächsische Staatseisenbahnen) in 1917/18 for express train services.

After a number of four-cylinder compounds had been taken into service in Saxony, the Saxon XVIII H appeared with a three-cylinder engine based on a Prussian prototype.

The newly formed Deutsche Reichsbahn took all 10 locomotives in 1925 over and gave them the numbers 18 001–010.

Because the trains on the Central Mountain routes were largely hauled by the powerful successor class, the Saxon XX HV (DRG Class 19.0), the Saxon XVIII Hs were mainly deployed on less hilly lines of Dresden–Leipzig and Dresden–Berlin.

After the Second World War the nine remaining engines were concentrated in Dresden and were mostly used to haul express services to Berlin.
