It is part of the traditional region of Follo. The administrative centre of the municipality was the village of Kolbotn. The municipality of Oppegård was separated from the municipality of Nesodden on 1 July 1915. Oppegård municipality had an area of 37 square kilometres (14.3 sq mi), hence it was the smallest municipality in Akershus by area.
Within Oppegård, there is an eponymous village.
The municipality (originally the parish) is named after the old Oppegård farm (Old Norse: Uppigarðr), since the first church was built here. The first element is uppi which means "upper" and the last element is garðr which means "farm". (The farm is probably a part of an older and bigger farm.)
The coat-of-arms were granted on 6 August 1976. The arms show 17 gold triangles on a black background. The 17 triangles symbolize 17 trees, which again symbolize the 17 old farms in the municipality. Most of the farms lie in an area called Svartskog ('black forest'), so the arms are canting arms.
Oppegård has been populated since the end of the last ice age. Archeological remains of hunter-gatherer societies dating back to 5000–6000 BCE have been found, as well as the remains of agricultural settlements from 1000 to 2000 BCE. The main southern roads connecting Oslo to Sweden and Denmark have passed through Oppegård since the Iron Age.
The former municipality was created from the eastern part of the municipality of Nesodden in 1915. At the time, the population of Oppegård was only 600. The 1960s and 1970s saw a population boom, as larger housing projects established the Oppegård villages as suburbs of Oslo. The commercial centres along the main railroad axis is examples of the functionalist architecture characteristic of that period of urbanization in Scandinavia.
Arctic explorer Roald Amundsen lived in Svartskog and his house is now a museum, administered by the municipality. Svartskog is also home to a medieval stone church, and is likely the oldest settlement in Oppegård.
Since 1968, coinciding with the population boom, the Conservative Party of Norway (Høyre) has held either a majority or plurality of representatives in the municipal council. Several leading politicians for Høyre began their political careers as mayors of Oppegård, including Rolf Presthus (mayor from 1968 to 1970, Conservative Party Leader and Minister of Finance) and Jan Petersen (mayor from 1975 to 1981, Conservative Party Leader and Minister of Foreign Affairs). Oppegård is demographically an urban middle class area, demographically similar to Bærum and Asker and a traditional stronghold for Høyre.

Oppegård is located at the eastern coast of Bunnefjorden (originally called "Foli", like the Årungen lake to the south), which is an arm of Oslofjord. It includes the villages Oppegård, Svartskog, and Kolbotn. The landscape is dominated by a vast part of the north–south oriented lake Gjersjøen, which roughly divides the district into western and eastern sections. The lake Kolbotnvannet is located here as well. The undeveloped areas are largely covered by forest.
Oppegård is a largely residential suburb of Oslo, but also a business hub. It hosts the Norwegian headquarters of several larger corporations (including Kodak and IBM) within its borders. Tax revenues from large corporations made Oppegård one of Norway's richest municipalities in the 1980s and 1990s. These revenues, and the wealth they brought, were lost in the 2000s when corporations were made to pay taxes directly to the national government, rather than the local government.
Commuter trains connect Oppegård to Oslo, and makes the neighbourhoods close to the train stations (Rosenholm, Kolbotn, Solbråtan, Myrvoll, Greverud, and Oppegård) popular residential areas.
