Württembergische Metallwarenfabrik (or WMF AG, "Metalware Factory of Wuerttemberg") is a German tableware manufacturer, founded in 1853 in Geislingen an der Steige by the miller Daniel Straub and the brothers Schweizer.

WMF was originally called Metallwarenfabrik Straub & Schweizer and was opened as a metal repairing workshop. Through mergers and acquisitions, by 1900 they were the world's largest producer and exporter of household metalware, mainly in the Jugendstil, or Art Nouveau style, designed in the WMF Art Studio under Albert Mayer, sculptor and designer, who was director from 1884 to 1914.

In 1880 after Metallwarenfabrik Straub & Schweizer merged with another German company, it was renamed as the Württembergische Metallwarenfabrik. WMF acquired the Polish metalware factory Plewkiewicz inWarsaw in 1886, which then became a subsidiary of WMF around 1900.
