Dehiwala-Mount Lavinia (Sinhala: දෙහිවල-ගල්කිස්ස, romanized: Dehivala-Galkissa; Tamil: தெஹிவளை-கல்கிசை, romanized: Tehivaḷai-Kalkicai), population 245,974 (2012), is a large municipality in Sri Lanka, covering 2,109 ha (5,210 acres). It lies south of the Colombo Municipal Council area and is separated from it by the Dehiwala canal which forms the northern boundary of DMMC. Its southern limits lie in Borupana Road and the eastern boundary is Weras Ganga with its canal system and it includes some areas to its east (Pepiliyana, Gangodawila and Kohuwala). This town has experienced extensive population growth and rapid industrialisation and urbanisation in recent years. It is home to Sri Lanka's National Zoological Gardens, which remains one of Asia's largest. Colombo South Teaching Hospital, Kalubowila and Colombo Airport, Ratmalana are some important landmarks in this area. Dehiwela-Mount Lavinia and Sri Jayawardenapura Kotte being two large suburban centres of the city of Colombo function together as one large urban agglomeration in the Region (Western Province). The overspill from the City in residential and commercial uses of land has rapidly urbanised these suburban centres. Dehiwela-Mount Lavinia and Sri Jayawardenpaura along with Colombo Municipal Council form the most urbanised part of the core area of the Colombo Metropolitan Region. Dehiwala and Mount Lavinia lie along the Galle Road artery, which runs along the coast to the south of the country.

There are many stories about the history of this area. One of those is Diya Wala which means a dip or hole filled with water. In the past this area was full of ponds and lakes; thus it became known as Diyawala (an area filled with water) and later on it became Dehiwala. Another story in regard to this name is that this area has many lime trees or a forest of lime trees and people called it Dehiwala. It is said that the king of Kotte filled all his lime requirements from this area.

Before colonisation of the maritime region by the Portuguese, the area covered by the present DMMC was part of the Kingdom of Kotte. It comprised a number of villages such as Pepiliyana Nedimala, Attidiya and Kalubowila, while Ratmalana and areas south of Dehiwala were together one large expanse of marshland, and scarcely populated.

During the Portuguese occupation, the Kingdom of Kotte was ruled by king Don Juan Dharmapala, and it encompassed the above-mentioned villages. Early records also indicate that in the year 1510 AD the village of “Galkissa” is mentioned and named after the rocky mound (Lihiniyagala) protruding into the Bay. Fascinating tales are woven round this rock and the village “Galkissa”. The Dutch invaders called the mound “the pregnant wench”.

With the arrival of the Dutch in the early seventeenth century, a more organised administrative structure was in place, whereby a broad-based taxation and legal system evolved.

However, it was only during British occupation (19th Century) that a Provincial administrative (Kachcheri) system and a form of Local Government developed. When the second Governor of Ceylon, Sir Thomas Maitland, acquired land at "Galkissa" (Mount Lavinia), he decided in 1806 to construct a personal residence there. Maitland fell in love with Lovina Aponsuwa, a local mestiço dancer, and continued a romantic affair with her until he was recalled to England in 1811. The Governor's mansion, which he named "Mount Lavinia House" is now the Mount Lavinia Hotel and the village that surrounded the building has subsequently developed into a bustling area, taking its name from the Governor's mistress, Lovina. Later, the area assumed the name of Mount Lavinia alluding to the factual story of a romance between the then British Governor Thomas Maitland (1805–1812) and a dancing girl called Lovina of the area.

Dehiwela, Mount Lavinia attained Municipal status in December 1959. Dehiwela Mount Lavinia as a Local body of 6 wards extending over a land extent of only 16.3 km (1,630 ha (4,000 acres)). Due to rapid urban growth and for administrative reasons this area was extended and divided into 19 wards in 1959 and given Municipal status. Later in 1967 the municipality was increased to an area of approximately 2,109 ha (5,210 acres) was apportioned into 29 wards, as it exists today.

As the Dehiwala-Mount Lavinia area lies on the coastal plain the land is mostly flat and undulating towards the inland areas. A significant feature is the large extent of wetlands around the Weras Ganga (river) and Bolgoda Lake, the two major water bodies. The Bellanwila and Attidiya marshes are noteworthy for their biodiversity and as such are considered as an ecological protected zone. Lying in the wet zone, the Dehiwala-Mount Lavinia area receives an average annual rainfall between 2,000–3,000 mm (79–118 in) mainly during the southwest monsoon and the intermonsoon periods. The mean average day temperature is around 28 °C (82 °F) and the average maximum between 30.5 and 31 °C. The minimum night temperature varies from 26 °C to 27 °C.
