Nurmijärvi (Finnish pronunciation: [ˈnurmiˌjærʋi]) is a municipality in Finland, located in the southern interior of the country.

In recent decades, Nurmijärvi has been one of the fastest growing municipalities in the Helsinki Metropolitan Area and in Finland as a whole.

The Nurmijärvi church village is the administrative centre of the parish, although population growth is clearly concentrated in Klaukkala.

The area of what is now Nurmijärvi was inhabited in prehistoric times, which refers to archaeological finds dating back to 4500–3500 BC.

[7] Administratively, Lake Nurmijärvi has been formed by combining the districts of Loppi, Vihti and Helsinki parish.

Horticultural crops have also been heavily cultivated and, for example, almost half of the wild cabbage harvest in Finland is produced in Nurmijärvi.

[8] The first industrial plants were born in the late 19th century, including Finland's first pharmaceutical factory founded by pharmacist Albin Koponen in Nurmijärvi in 1899.

[7] The main products of the drug plant were filizine extracted from male fern root rhizomes, which were sold as Diphyllobothrium latum and cestoda medicines called Filisin and Filicon.

However, migration to Nurmijärvi began to accelerate around the middle of the decade and the focus of settlement shifted to the southern parts of the municipality.

Of these, the growth of Klaukkala and church village, in particular, has been based almost exclusively on the vicinity of the Helsinki metropolitan area.

The Kuhakoski rapids, located in the village of Perttula and flowing into Lake Valkjärvi, is also significant in terms of industrial history and at the same time a popular attraction with its waterfall.

[14] The most important traffic route through Nurmijärvi is Finnish national road 3 (Vt 3; E12) between cities of Helsinki and Tampere.

Highway 3 is joined by Finnish national road 45 (Kt 45) on the Hyvinkää side from Hyrylä in Tuusula and through the eastern part of Nurmijärvi, and Finnish national road 25 (Vt 25) between Hanko and Porvoo passes through the northern part of the municipality near the Röykkä village.

[29][30] In the 1980s, the cultural dishes of Nurmijärvi parish were called pastries with raisin soup, a roast beef cured slowly in mild heat, berry cream and sweetened potato casserole.

[32] Characteristic features of the Nurmijärvi dialect are the widening of diphthongs, the r-sound as a weak equivalent of t, and the tt (long /t/) representation of the ts combination.
