Hurum was a municipality in Buskerud county, Norway. As of 1 January 2020 Hurum has merged with the municipalities of Røyken and Asker to form the new Asker Municipality located in the newly formed Viken county. The administrative centre of the municipality is the village Sætre. The municipality of Hurum was established on 1 January 1838 (see formannskapsdistrikt). The small village of Holmsbu was granted town status in 1847, but it did not become a municipality of its own. It lost its town status on 1 January 1964.

Hurum was once suggested as the location for the new national airport of Norway. The plan was, however, abandoned, due to fears of too much fog in Hurum, and the main airport is now situated at Gardermoen in Akershus.

The Old Norse form of the name was Húðrimar. The meaning of the first element (Húð) is unknown and the last element is the plural form of rimi which means "ridge".

The coat-of-arms is from modern times. They were granted on 2 February 1979. The arms show two blue wavy lines on a silver background. This was chosen because the municipality is on a peninsula between two fjords: Oslofjord and Drammensfjord. At the same time the arms are based on the arms of the Huitfeldt family, who played a major role in the local history. The family used a single bend as arms.

The municipality borders Røyken to the north. To the west the coastline is located close to the eastern coast of Vestfold with Svelvik. It is connected to the eastern side of the Oslofjord via Oslofjordtunnel, one of the longest undersea tunnels of its kind in Northern Europe. The tunnel is 7.2 kilometres (4.5 mi) long and connects Hurumhalvøya to Akershus county.

Hurum is located on the southern part of Hurumhalvøya, which is the peninsula between the Oslofjord and Drammensfjord. The administrative centre is the village of Sætre, which together with Tofte are one of the two most populated villages in Hurum.

Hurum Church (Hurum kirke) is the parish church for Hurum. This is a medieval era church dating from ca. 1150. The edifice is constructed of stone and has 150 seats. The original church was ravaged by fire the night after Christmas Day 1686. The following year the church received a new roof and turret. In 1849 the church was extensively rebuilt. The interior has undergone a number of changes in the course of time. The cemetery is surrounded by stone wall and has a chapel from 1938. Naval hero and native son, Ivar Huitfeldt (1665-1710) was buried in the church yard. The pulpit was received as a gift from his wife, Kirsten Røyem Huitfeldt (1671–1750).

On 9 May 2016, a referendum on the status of the municipality was held, with a majority of voters voting to merge Hurum with Røyken and Asker to create a new and larger Asker. Subsequently, on 21 June the same year, a majority of municipal councillors voted in favor of applying for the merger, which was subsequently accepted by the local councils of both Røyken and Asker. It was determined that the municipalities would officially merge on 1 January 2020. During the 2019 Norwegian local elections, voters in the three municipalities voted on who they wanted to govern the new municipality rather than their three original municipalities, the newly elected councillors took their seats on the same day as the municipalities merged.
