Heinrich I, Count of Pegnitz (c. 1000 – c. 1043) is a contested early ancestor of the House of Wittelsbach.
He was born in Pegnitz to allegedly either Henry von Schweinfurt, Margrave of the Nordgau or Count Berthold of Schweinfurt (and either of their respective spouses).
Thus meaning he was the paternal great-grandson or grandson of Arnulf, Duke of Bavaria, making him and the House of Wittelsbach descendants of the Luitpoldings.
Heinrich I died circa 1043 in Scheyern.
