Nikolaus von Schönberg (11 August 1472 – 7 September 1537) was a German Catholic cardinal and Archbishop of Capua.

Impressed by the speeches held by Savonarola in Pisa in 1495, Schönberg became a priest in 1497 and a member of the Ordo Praedicatorum (Dominican Order) on 31 October 1498.

George, Duke of Saxony, made Schönberg his procurator for the Fifth Council of the Lateran (1512–1517).

Pope Leo X sent him as papal legate around Europe to find support for a crusade against the Ottoman Turks.

Other missions sent him to Maximilian I, Holy Roman Emperor, at Innsbruck, to the courts of Hungary, Poland, Muscovy, and to the Grand Master of the Teutonic Knights, Albert of Brandenburg.
