Wilhelm Meinberg (1 March 1898 – 8 February 1973) was a German Nazi Party politician and agricultural expert who served as the head of the Reichsnährstand and on the board of directors of the industrial conglomerate Reichswerke Hermann Göring during the Second World War.

He attended the Realgymnasium in Unna, obtained his Abitur and completed an agricultural apprenticeship in Brandenburg and Mecklenburg before enlisting in the Imperial German Army in 1916 and serving with Pioneer Battalion 15 in the First World War.

Released from captivity in October 1919, in November he became a member of the Deutschvölkischer Schutz- und Trutzbund, the largest and most active antisemitic organization in the Weimar Republic.

He also joined the conservative German National People's Party and, in 1923, became a farmer in Wasserkurl and founded a Stahlhelm group of war veterans, which took part in the fighting during the occupation of the Ruhr in the same year.

However, Meinberg intrigued to replace Darré as Reich Peasant Leader while he was on a leave of absence, and a court of honor proceeding was instituted against him.

[10] In 1941, Göring, in his capacity as the Plenipotentiary for the Four-Year Plan, appointed Meinberg to be the Sonderbeauftragter (Special Representative) for coal transport.

[12] Under his leadership, the party turned even further to the right, calling for West Germany's withdrawal from NATO and the Common Market, and advocating the creation of an authoritarian, one-party state similar to the Third Reich.
