The town of Svelvik is located by the Svelvik River, a narrow and steep strait of 200 meters between the inner and outer part of the Drammensfjord, which is almost closed by the Svelvik moraine across the fjord. The settlement in the municipality is concentrated in the coastal areas, especially in the three settlements: Svelvik, with 3,953 inhabitants in 2020, Berger with 1,100 inhabitants and Nesbygda with 1,031 inhabitants. The landscape is rising and in places steep up from the coastline, and there are large agricultural areas and many wooded hills.

Strømm and Svelvik belonged to Hurum parish until 2 March 1861. Svelvik became a charging station in 1845 as a sailing ship town and winter port for Drammen. Svelvik municipality decided in 1998 that the town Svelvik can use the term city.

Large parts of Svelvik center are older wooden houses, and are included in the NB! Register, the National Heritage Board's list of urban environments in Norway that have a national cultural-historical conservation interest.

The name Svelvik comes from Old Norse Sverðvík. The first part is uncertain and may go back to older * Sverfð- to Old Norse sverfa «swirl, go in a circle», or a general meaning «stream». Another interpretation is "bow" around the coastline of Hurumlandet.

In 2012, the high-voltage masts in Svelvik and at Verket were illuminated with resp. red and green to signal positive development.
