Larvik is a city in Norway at the end of the Lågen or Numedalslågen river in the county of Vestfold. It is an important port and lumber center on the southeastern coast, which is easily accessible via the Larvik Fjord. Ships regularly sail from there to all over Europe and in 1997 the Port of Larvik was appointed the Regional Port of its region of Norway. The city is also the birthplace of Thor Heyerdahl, a well known anthropologist with controversial theories about transatlantic contact between ancient civilizations. The city has a population of over 40,000 people and is only 130 kilometers from Oslo, the capital of Norway.

Larvik is also the name of the largest birch forest in Norway, the northernmost birch forest in the world.
