Đà Lạt or Dalat, (pop. 206,105 as of 2009, of which 185,509 are urban inhabitants) is the capital of Lam Dong province in Vietnam. The city is located 1,500 m (4,900 ft) above sea level on the Langbiang Plateau in the southern parts of the Central Highlands (in Vietnamese, Tây Nguyên). In Vietnam, Da Lat is a popular tourist destination.

Da Lat’s specific sights are pine wood (forming the name: “City of thousands of pine trees”) with twisting roads and tree marigold (Vietnamese: dã quỳ) blossom in the winter. The city’s temperate weather stands in contrast to Vietnam’s otherwise tropical climate. Mist covering the valleys almost year-round leads to its name “City of eternal spring”.

Da Lat is also known as an area for scientific research in the fields of biotechnology and nuclear physics.
With its year-round cool weather, Da Lat supplies temperate agriculture products for all over Vietnam, for example: cabbage and cauliflower. Its flower industry produces two typical flowers: hydrangea (Vietnamese: cẩm tú cầu) and golden everlasting (Vietnamese: hoa bất tử). The confectionery industry offers a wide range of mứt, a kind of fruit preserve made from strawberry, mulberry, sweet potato, and rose.

According some sources, the name derives from the acronym of the Latin phrase 'Dat Aliis Laetitiam Aliis Temperiem' ("Giving Pleasure to Some, Freshness to Others"), which the French colonial government used in their official emblem of Đà Lạt. In reality, the name Da Lat derived from the language of the local ethnic group Lạt and its original meaning is "Stream of the Lạt," and the acronym above is in fact a backcronym.

The French endowed the city with villas and boulevards, and its Swiss charms remain today. Hébrard included the requisite health complex, golf course, parks, schools, and homes but no industry. The legacy of boarding schools where children from the whole of Indochina were taught by French priests, nuns, and expatriates lasted until the end of French rule. There were seminaries of Jesuits (such as Pius X Pontifical College) and other orders. The elite Vietnamese National Military Academy graduated its first class of future leaders in 1950. There was an aviation school at Cam Ly Airport.

In the mid-1950s, the Vietnamese Scout Association established their national training grounds at Đà Lạt.
The only major involvement Da Lat had during the Vietnam War was within the 1968 Tet Offensive. Fierce battles raged from January 31 to February 9, 1968. Most of the fighting took place between the South Vietnamese MP units stationed in Đà Lạt and the Việt Cộng (VC) forces. Defeats and victories alternated between the two during the sporadic yet intense battles. However, the South Vietnamese MPs were eventually able to regain control of Đà Lạt. It is stated that around 200 VC were killed-in-action (KIAs) during this battle. Although South Vietnamese MP forces were known to have significantly fewer KIAs, their injured list grew steadily throughout the engagement due to periods of low supplies and support. What ultimately saved the South Vietnamese MPs was the fact that they held strong defensive positions throughout Đà Lạt from the beginning to the end of the battles.
