Hermann Weinsberg, also known as Hermann von Weinsberg (1518–1597) was a city councillor in Cologne and a diarist whose autobiographical writings, long obscure, are now considered to be of historical importance.

Weinsberg was born in Cologne on 3 January 1518, the oldest son of a wine merchant.

He was educated at the school of the Brethren of the Common Life in Emmerich am Rhein (1531–1534), and at Cologne University (1534–1543), where he held a scholarship and took the degrees Bachelor of Arts, Master of Arts, Bachelor of Law and Licentiate of Law.

The writings of Hermann von Weinsberg comprise a family history, Das boich Weinsberg, and a three-volume autobiography consisting of the retrospective Liber Juventutis (1518–1578) and the more diaristic Liber Senectutis (1578–1588) and Liber Decrepitudinis (1588–1597).

These manuscripts were discovered in the archives during the 19th century, and various selections have since been published under the title Das Buch Weinsberg (1886, 1898, 1926, 1961).
