Siegfried von Feuchtwangen is the fifteenth large-Master of the teutonic Ordre (1303 - 1311). It was born in Franconie in the family from Konrad von Feuchtwangen.

It takes the load of large-Master following the abdication of his predecessor Gottfried von Hohenlohe, magistère of this last being marked by dissensions within the Order.

Under its magistère, the Order takes possession of the town of Danzig in 1238 under pretext that the Polish had not paid the allowance promised with the Order for its assistance against the Margrave S the previous year. The Order will also annex in the following years the Pomérélie thanks to an agreement made with the Margrave of Brandebourg: Waldemar. The emperor Henri VII confirms this possession in 1311.

At the end of its magistère, Siegfried transfers the general headquarter about Venice to the teutonic Forteresse from Marienbourg.
