Re is a former municipality in Vestfold county, Norway. The 225-square-kilometre (87 sq mi) municipality existed from 2000 until its dissolution in 2020. The area is now part of Tønsberg Municipality. The administrative centre was the village of Revetal. Other villages in the municipality included Ramnes, Brekkeåsen, Bergsåsen, Gretteåsen, Undrumsdal, Fon, Vivestad.

Prior to its dissolution in 2020, the 225-square-kilometre (87 sq mi) municipality was the 316th largest by area out of the 422 municipalities in Norway. Re had a population of 9,730. The municipality's population density is 43.3 inhabitants per square kilometre (112/sq mi).

The river Aulielva ran through the municipality. The highest point in Re was Snippane with an elevation of 400 m (1,312 ft). Snippane was located along the border with Lardal Municipality, about 3 kilometres (1.9 mi) south of the village of Hof.

The municipality was established on 1 January 2002 when the two neighboring municipalities of Ramnes and Våle were merged to form one large municipality called Re.

On 1 January 2020, Re Municipality was dissolved and new borders were drawn for the municipalities of Horten, Tønsberg, and Holmestrand:

• the 691-decare (171-acre) area that is on the northeast coast Re Municipality, including the island of Langøya, was transferred into Holmestrand Municipality
• the 128-decare (32-acre) Haugan area was transferred from Horten Municipality to Re
• the 388-decare (96-acre) Nykirke/Pauliveien area was transferred from Re to Horten Municipality
• the 318-decare (79-acre) west Skoppum area was transferred from Re to Horten Municipality (creating a small exclave for the Råen farm inside Horten)
• the remaining portions of Re Municipality was merged into Tønsberg Municipality

The municipality is named after an old name for the district, Re (Old Norse: Ré). The name is related to the old German word reihe which means "line" or "row", referring to the local geological formation called Raet.

The coat of arms was granted on 31 August 2001 in preparation for the establishment of the new municipality on 1 January 2002. It was determined by a public competition and a public vote among inhabitants of the new municipality. The official blazon is "Vert, an escarbuncle Or" (Norwegian: I grønt en gul liljehaspel). This means the arms have a green field (background) and the charge is a five-pointed escarbuncle. The charge has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used. The green color in the field symbolizes the importance of nature and agriculture. The five-pointed design has a long history in the area and it symbolizes unity and to point back in time to the historic battles fought at Re. The five points represent the five parishes within Re. The arms were designed by Arvid Steen. The municipal flag has the same design as the coat of arms.

The Church of Norway had five parishes (sokn) within the municipality of Re. It was part of the Nord-Jarlsberg prosti (deanery) in the Diocese of Tunsberg.
