Henry XV of Bavaria

Henry XV (1312–1333), called the Natternberger after his favourite Natternberg Castle, was a Wittelsbach Duke of Lower Bavaria, son of Duke Otto III, born shortly before his father's death. He grew up under the tutelage of his cousin Emperor Louis IV and ruled jointly with his cousins Henry XIV and Otto IV until the partition of 1331 gave him Deggendorf and the surrounding lands.

In 1327 he stood unsuccessfully as a candidate for the Hungarian crown. He married Anna of Austria and died childless at Natternberg on 18 June 1333.
