The Province of Uusimaa (Finnish: Uudenmaan lääni, Swedish: Nylands län, Russian: Нюландская губерния) was a province of Finland from 1831 to 1997.
[1] It was established in 1831, when the County of Nyland and Tavastehus was divided into the Häme Province and Uusimaa Province.
In 1997 it was merged with the Kymi Province and the southern parts of the Häme Province into the new Southern Finland Province.
[2] The beginnings of the Province of Uusimaa lie in the Swedish governance reforms of 1634.
At that time, new counties were established also in the territories of Finland.
