Bruno of Augsburg (or Brun) von Bayern (c. 992 – 1029) was the son of Henry II, Duke of Bavaria (the Wrangler or Quarrelsome) and Gisela of Burgundy.

When the revolt failed, Bruno fled to Bohemia and then stayed for a time at the court of his brother-in-law, King Stephen I of Hungary.

As a bishop, he encouraged King Stephen I of Hungary's efforts to convert rebellious pagans to the new faith.

The diocese of Augsburg attained great splendour under Bishop Bruno (1006–1029); he restored a number of ruined monasteries, founded the church and college of St. Maurice, placed Benedictine monks in the collegiate church of St. Afra, and added to the episcopal possessions by the gift of his own inheritance of Straubing.

[5] Bruno escaped across the Alps, taking the young Henry with him, and joined Conrad II in Italy.
