Georg Giese[a] (2 April 1497 – 3 February 1562) was a Hanseatic merchant, who managed his family's office at London's Steelyard for at least 12 years and is noted for having had his portrait painted by Hans Holbein the Younger.

[5] Situated in the Steelyard, the London branch of the Hanse, the Giese family office was part of an enclave where Hanseatic and foreign merchants congregated.

The painter, Hans Holbein the Younger, produced portraits of wealthy merchants, including Giese and others based at the Steelyard.

Yet another document from the Danzig Assembly (dated 30 October 1535) identifies the merchant mark of "Jorg Gisse," which scholars believe refers to Georg Giesse, and which is the same symbol as can be seen on the seal depicted on Giese's desk in Holbein's painting.

[8] The portrait is noted for the decor and objects that surround Giese in his London Office, all of which attest to his wealth and status as a member of the rising merchant class.

While Giese was stationed at the Steelyard during the 1530s, the merchant members located there sat for a series of portraits by Hans Holbein the Younger.

In the background and on the desk, letters, stamps and strips of sealing wax indicate his connections to both his family and a network of traders operating in the region.
