Frederick IV of Hohenstaufen (1145 – 1167) was duke of Swabia, succeeding his cousin, Frederick Brabarossa, Holy Roman Emperor, in 1152. He was the son of Conrad III, king of Germany (not crowned emperor) and Gertrude of Sulzbach and thus the direct heir of Germany. However, on his dying bed, Conrad III advised the electors of the Empire to choose Frederick Barbarossa instead.
