Frankenthal (Pfalz) (Palatine German: Frongedahl) is a town in southwestern Germany, in the state of Rhineland-Palatinate.

In 1119 an Augustinian monastery was built here, the ruins of which — known, after the founder, as the Erkenbertruine — still stand today in the town centre.

Some of them were important carpet weavers, jewellers and artists whose Frankenthaler Malerschule ("Frankenthal school of painting") acquired some fame.

In 1621 it was garrisoned by English soldiers under Sir Horace Vere and besieged by the Spanish during the Thirty Years' War, and then successively occupied by troops of the opposing sides.

To establish trade, a port was built between 1772-1781, numerous factories were opened and mulberry trees were planted for silk production.
