Prince Radu of Romania (born Radu Duda on 7 June 1960, formerly known as Prince Radu of Hohenzollern-Veringen from 1999 to 2007) is the husband of Margareta of Romania, head of the House of Romania and a disputed pretender to the former Romanian throne. On 1 January 1999, he was given the name, not title, of "Prince of Hohenzollern-Veringen" by Friedrich Wilhelm, Prince of Hohenzollern, the Head of the Sigmaringen branch of the Hohenzollern family. He has also called himself "Radu Hohenzollern-Veringen-Duda". Since 2007, when he had his legal name changed from "Radu Duda" to "Radu al României Duda", Radu no longer uses the name of Hohenzollern.
