Jens Hermansson Juel (8 January 1580 at Refstrup – died 26 March 1634 at Bøvling) was a Danish nobleman who served as Governor-general of Norway from 1618 to 1629.

He advanced quickly, being given major tasks: Royal Treasurer (responsible for accounting, payment and collection of customs duties and taxes, as well as management of state property, including forests, roads and buildings) beginning in 1609, member of the Danish national council from 1616 and assignment to serve on several diplomatic missions.

King Christian IV was occupied with the Thirty Years' War which left Juel with substantial latitude to apply his own judgment.

He enacted a garrison tax in 1627, which financed the manning of fortresses at Akershus, Båhus, Bergen and Trondheim, and served as the foundation of an independent Norwegian defense organization, based on a strengthened peasant militia.

Juel was also active in husbanding his private wealth through lending while he served in Oslo, gaining ownership of a number of Norwegian estates, and also acquiring lands in Denmark.
