'''Nyland and Tavastehus County''', or '''Uusimaa and Häme Province''',{{efn|{{Langx|sv|Nylands och Tavastehus län}}, {{Langx|fi|Uudenmaan ja Hämeen lääni}}. In Finnish contexts, ''lääni'' or ''län'' is usually translated as 'province', while in Swedish contexts, ''län'' is usually translated as 'county'.<ref>{{Cite book |title=Country Compendium: A companion to the English Style Guide |date=May 2025 |publisher=European Union |pages=45,145|url=https://commission.europa.eu/document/download/2d706ca2-0927-4a58-a0f4-ae76aae2d84c_en}}</ref>}} was a [[Counties of Sweden|county of the Swedish Empire]] from 1634 to 1809, and a [[Provinces of Finland|county of Grand Duchy of Finland]] from 1809 to 1831.

In 1775 whole northern part of the county (later [[Central Finland]] region) was transferred to the new [[Vaasa Province|Vasa County]]. Also a part of historical [[Satakunta (historical province)|Satakunta]] was added to the Nyland and Tavastehus County from the [[Åbo and Björneborg County]], while Upper Hollola was transferred to the new [[Kymmenegård County]].

By the [[Treaty of Fredrikshamn]] in 1809 [[Kingdom of Sweden (1721–1809)|Sweden]] ceded all its territories in Finland, east of the [[Torne (Finnish and Swedish river)|Torne River]], to Russia. The county still continued to exist as a province of the new autonomous [[Grand Duchy of Finland]] until 1831, when it was split to Tavastehus County ([[Häme Province]]) and Nyland County ([[Uusimaa Province]]).<ref>{{Cite web |title=Tavastehus län |url=https://uppslagsverket.fi/sv/sok/view-170045-TavastehusLaen |access-date=2025-09-02 |website=Uppslagsverket Finland}}</ref>
