Ullensvang is a municipality in Vestland county, Norway. It is located in the traditional district of Hardanger. The administrative centre is the town of Odda. Some of the notable villages in the municipality include Lofthus, Utne, Vikebygd, Alsåker, Botnen, Eitrheim, Håra, Røldal, Seljestad, Skare, Tyssedal, Jondal, Herand, Kysnesstranda, and Torsnes.

The main inhabited part of Ullensvang municipality lies just to the west of Hardangervidda National Park, which covers most of the Hardangervidda plateau, Europe's largest mountain plateau. Most inhabitants live in the narrow coastal mountainsides and valleys along the Hardangerfjorden and Sørfjorden. The largest urban areas in Ullensvang are Odda, Kinsarvik, Jondal, and Lofthus. The Norwegian National Road 13 and the European route E134 are the two main roads through the municipality. National road 13 crosses the Hardangerfjorden via the Hardanger Bridge in the far northern part of the municipality.

The 3,230-square-kilometre (1,250 sq mi) municipality is the 12th largest by area out of the 356 municipalities in Norway. Ullensvang is the 104th most populous municipality in Norway with a population of 11,148. The municipality's population density is 3.8 inhabitants per square kilometre (9.8/sq mi) and its population has decreased by 2.5% over the previous 10-year period. The number of inhabitants has shown a decrease of several hundred people since 1980. This development can be seen in light of the general depopulation of rural Norway.

In 2016, the chief of police for Vestlandet formally suggested a reconfiguration of police districts and stations. He proposed that the police station for Ullensvang og Eidfjord be closed.

As of Q3 2024, a copy of a stave church is nearing completion, above the centre of Odda.

The municipality (originally the parish) is named after the old Ullensvang farm (Old Norse: Ullinsvangr) since the first Ullensvang Church was built there. The first element is the genitive case of the name of the Norse god Ullin (an alternate form of the name Ullr). The last element is vangr which means "field" or "meadow". Prior to the 2020 municipal merger, this municipality was called Ullensvang herad, but after the merger it was called Ullensvang kommune.

The original coat of arms was granted on 8 November 1979 and it was in use until 1 January 2020 when a new version of the arms was put into use. The official blazon was "Gules, a bar Or between three fleur-de-lis of the same" (Norwegian: I raudt ein gull bjelke følgd av tre gull liljer, to over og ei under bjelken). This means the arms have a red field (background) and the charge is a horizontal stripe across the middle, with three fleur-de-lis designs (two above the stripe, one below). 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 design of the arms was derived from the arms of Sigurd Brynjulvsson Galte, a medieval nobleman from the area. They can be seen on his gravestone from 1302 at the local church. As it is the oldest gravestone in the church, the arms were well known in the village, hence the choice for the arms of this knight as municipal arms. The arms were designed by Magnus Hardeland. The municipal flag has the same design as the coat of arms.

A new coat of arms was granted in 2019 for use starting on 1 January 2020 after Odda and Jondal municipalities were merged with Ullensvang. The new arms were the same design as the previous arms, but they incorporated the colors from the old arms of Odda Municipality (blue and white instead of red and gold). The official blazon for the new arms is "Azure, a bar argent between three fleur-de-lis of the same" (Norwegian: I blå ein sølv bjelke følgd av tre sølv liljer, to over og ei under bjelken).

The Church of Norway has eight parishes (sokn) within the municipality of Ullensvang. It is part of the Hardanger og Voss prosti (deanery) in the Diocese of Bjørgvin.

On 1 January 1838, the large parish of Kinsarvik was established as a municipality (see formannskapsdistrikt law). The large parish was made up of the main parish and the annex of Ullensvang. On 1 January 1869, Ullensvang became the main parish and Kinsarvik became an annex to Ullensvang. At this time the municipality changed its name to Ullensvang. On 1 January 1882, a small area of Ullensvang (population: 22) was transferred to the neighboring municipality of Vikør. On 1 July 1913, the municipality of Ullensvang was divided into three parts: the northwestern part became Kinsarvik Municipality, the southern part became Odda Municipality, and the rest remained as Ullensvang Municipality, albeit much smaller. This left Ullensvang with 1,941 residents.

During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the following areas were merged into one large municipality: all of Ullensvang Municipality, all of Eidfjord Municipality, and most of Kinsarvik Municipality (except for the Lussand-Kvanndal area which went to Granvin Municipality). The newly enlarged municipality was named Ullensvang. On 1 January 1965, the Åsgrenda area of Kvam Municipality (population: 61) was transferred to Ullensvang. This new, large municipality of Ullensvang that was created in 1964-1965 was not long-lived. On 1 January 1977, the area that once was Eidfjord Municipality became its own municipality once again. This left Ullensvang with 3,937 residents.

On 1 January 2020, the three neighboring municipalities of Jondal, Odda, and Ullensvang were merged into a new, larger Ullensvang Municipality. At that time, the administrative centre was moved from the village of Kinsarvik to the larger town of Odda. On 1 January 2022, the Ytre Bu area of Ullensvang (population: 24) was transferred to the neighboring Eidfjord Municipality.

Ullensvang is Norway's biggest supplier of fruit, especially sweet cherries and apples. Every summer a cherry festival is held at Lofthus, where the Norwegian championship of cherry stone spitting is held. The record is 14.24 metres (46.7 ft) by S. Kleivkaas. Each May, a musical festival is held at Ullensvang Hotel (built in 1846), when musicians from all of Norway come to the village. The famous composer Edvard Grieg spent many summers at Lofthus, and the festival is held in his honor. During the summer, the population is doubled due to tourism. Attractions in addition to the previous mentioned, are the medieval Ullensvang Church at Lofthus (built around 1250) and Kinsarvik Church (built around 1150), several waterfalls such as the Skrikjofossen, the flowering season in May, and museums at Aga, Utne, and Skredhaugen.
