Jarlsberg
Jarlsberg was a former countship that forms a part of today's Vestfold county in Norway. The name translates as "Earl's Hill".
The former countships of Jarlsberg and Larvik were merged into a county in 1821. Jarlsberg and Larvik's County were renamed Vestfold in 1919.
Created in 1673 as Griffenfeldt Countship, it was after a few years known as Tønsberg Countship until 1684, when the name became Jarlsberg. Dating to 1681, the countship was associated with members of the Dano-Norwegian noble family, Wedel-Jarlsberg. The countship was abolished in 1893 in accordance with Norway's nobility law, but the manor is still in its own family.

Jarlsberg was originally created as a countship in 1673 for Peder Schumacher Griffenfeld, a Danish statesman and Chancellor of Denmark during the reign of King Christian V of Denmark. Schumacher received in 1671 an armorial grant with the name Griffenfeld. The creation involved that Count Griffenfeld, in addition to owning 14 percent of the countship's land, received large tax revenues and also the right to appoint all civil and ecclesiastical officials, including officers and judges, who would serve within the countship.- 1673-1676 Count Peder Schumacher Griffenfeld
