Larvik is a town and municipality in the province of Vestfold in Vestfold and Telemark county. It borders in the north on Kongsberg and Holmestrand, in the east on Sandefjord and Tønsberg, and in the west on Porsgrunn, Siljan and Bamble.

In connection with the municipal reform, the municipality was merged with Lardal municipality on 1 January 2018.


Larvik is a coastal municipality, which also includes large good agricultural areas, as well as forests and mountains. In the north-south direction, the municipality has an extent of approx. 40 km. The highest point is Vindfjell with its 622 meters (before the merger with Lardal, the highest point was Vettakollene 453 masl).

Rakkebåene and the lighthouse Svenner are well-known landmarks in the skerries outside the city. Larviksfjorden leads from the Skagerrak into the city.

Farrisvannet is 20.5 km long and has a depth of 131 meters. Topographically, Farrisvannet is a continuation of Larviksfjorden. The water is dammed up by the ridge at Farriseidet, so that the fjord becomes a lake. The fall of 22 meters from the lake to the sea was used for various types of industrial activities. On the outside of the row, a natural spring emerges, which constantly provides water for the production of Farris in bottles. Lake Farris also supplies drinking water to large parts of the former Vestfold county.

Hallevannet is another larger lake, located southwest of Larvik municipality. On the border with Sandefjord in the west is Goksjø.

One of the country's largest rivers, Numedalslågen, originating on the Hardangervidda, has its outlet in the sea east of the city. The lower part of Lågendalen, formerly Hedrum municipality, is part of Larvik.

The bedrock in the entire municipality is larvicite, a blue, crystalline deep rock. The rock is named after the town of Larvik, and in the entire southern part of Vestfold is located on this rock, which also means a lot financially.

Quaternary geologically, Larvik is characterized by the large end moraine, raet, which dominates large parts of the landscape in Østfold and Vestfold. Raet is under water from Jomfruland to Mølen, the southernmost in Larvik municipality, then it forms a diagonal across Brunlanes to Farriseidet before continuing through the neighboring municipalities in the direction of SE.

Raet dams up lakes, is important for the transport system and is the basis for agriculture.

Larvik is part of Gea Norvegica Geopark.

Larvik has a moderate coastal climate, with relatively mild winters and warm summer weather.
