Hans Holtermann (c. 1709 – 1781), also known as Hans Henrik Holtermann or Hans Henriksen Holtermann, was a Norwegian businessman and landowner.
Hans Holtermann was from a family of traders and whole merchants on the west coast of Norway. Holtermann's great-grandfather, Coert Holtermann, is believed to have first immigrated from Rothenburg in Germany to Bergen with his son Henrich Holtermann (1650-1730). They acquired citizenship in 1676 and became involved in trading. Hans Holtermann's father, Henrik Holtermann (1683-1728), acquired trading rights in Bergen. At that time there was no market town (kjobstad) in Sunnmøre and the Holtermans extended their privileges to Borgund and set up a trading post at Brunholmen that eventually became the nucleus of the town of Ålesund. Hans Holtermann operated as a trader in Molde and later at Vegsund in Borgund (now Ålesund). He may also have introduced dried and salted cod (klippfisk) production and trade to the area.
His first marriage was to Margaretha Knudsdatter Wiig (from Vik in Ørsta, 1692–1743). His second marriage was to Ingeborg Catharine (a.k.a. Cathrina, Cathrine) Hagerup (August 30, 1730 – 1796), the daughter of Bishop Eiler Hagerup. Holtermann was the brother-in-law of the magistrate Melchior Falch, who was married to a younger daughter of Bishop Hagerup. His son, Knut Holtermann, became a supreme court judge in Copenhagen (then also the capital of Norway).
Hans Holtermann purchased parts of the Giske estate circa 1750, and in 1760 Austrått manor in Ørland. Holtermann is believed to have paid 26,000 riksdaler for Austrått. The Austrått manor also included part or full ownership of a large number of smaller farms in the Ørland region. Hans Holtermann hosted Christian VI of Denmark on the King's famous journey through Norway in 1733.
