On the south coast of the island of Efate, in Shefa Province, Port Vila is the economic and commercial centre of Vanuatu. The mayor is Jenny Regenvanu of the Land and Justice Party, the first woman to hold the position, elected in August 2024. Her deputy is Marie Louise Milne, of the Green Confederation.

On 13 March 2015, Port Vila suffered extensive damage from Cyclone Pam.

Locally the town is most commonly referred to simply as "Vila", whether in French or Bislama [viˈla] or in English /ˈviːlə/ VEE-lə (not like English "villa").

The name of the area is Efil in the native South Efate language and Ifira in neighbouring Mele-Fila language. Vila is a variant of these names. Ifira is a small island in Vila harbour where many of the area's traditional landowners reside.

The area occupied by Port Vila has been inhabited by Melanesian people for thousands of years. In Autumn of 2004, an archaeological expedition known as Teouma discovered a burial site of 25 tombs containing three dozen skeletons of members of the Lapita culture. Pieces of ceramics found at the site were dated to the 13th century BC.

Efate Island was charted in 1774 by James Cook, who named it Sandwich Island. Cook's expedition did not land but noted the presence of good harbours and land suitable for European settlement. In late 19th century when the islands were known as the New Hebrides, the British were initially the dominant European presence, though by the 1890s, the economic balance had begun to favour the French, who established large plantations. French citizen Ferdinand Chevillard began buying and clearing land around Port Vila to be converted into the largest French plantation on the island. Instead, it was converted into the municipality of Franceville, which declared independence on 9 August 1889, though this only lasted until June of the following year.

It was the first self-governing nation to practice universal suffrage without distinction of sex or race. Although the population at the time consisted of about 500 native islanders and fewer than fifty whites, only the latter were permitted to hold office. One of the elected presidents was a US citizen by birth, R. D. Polk, a relative of American president James K. Polk.

After 1887, the territory was jointly administered by the French and the British. This was formalized in 1906 as an Anglo-French Condominium. During World War II, Port Vila was an American and Australian airbase.

In 1987, Cyclone Uma severely damaged the city. A powerful earthquake in January 2002 caused minor damage in the capital and surrounding areas. The city suffered massive damage from a category 5 cyclone named Cyclone Pam in March 2015, whose eye wall passed just to the east of Port Vila.

Vanuatu is still dependent on foreign aid, most of which comes from Australia and New Zealand, although in recent years aid has also come from China.

The day-to-day lingua franca in the capital city is Bislama. In addition, English and French are also widespread.

Among Vanuatu's 100 indigenous languages, many are spoken in the capital, as people from rural areas come to live in the city, either temporarily or permanently.

Christianity is the predominant religion across Vanuatu, followed by more than 90% of the population. The largest denomination is the Presbyterian Church in Vanuatu, followed by one third of the population. Roman Catholicism and the Church of Melanesia are also common, each about 15%. Cathédrale du Sacré-Cœur is a modern Roman Catholic cathedral in Port Vila. The seat of the Diocese of Port Vila, the church is dedicated to the Sacred Heart of Jesus. On October 5, 2020, The Church of Jesus Christ of Latter-Day Saints announced plans to construct a temple in the city, and the Baháʼí Faith community is also established in Port Vila.

The capital of Vanuatu has various sights to offer. There are several memorials, e.g. opposite the Parliament where two traditional totem poles and a monument representing a pig's tusk can be seen. The Presbyterian Church of Port Vila is an impressive and sightworthy building opposite the Independence Park. A colourful wall painting can be seen on the administration building opposite the market hall. Another noteworthy wall painting is on the façade of the post office. The City Hall of Port Vila is an oblong and sightworthy building on a hill in the city centre.

The Vanuatu Cultural Centre, hosting the Vanuatu National Museum, is located at the Saralana Park in front of the national parliament, close to the National Library and the Malvatumauri (Vanuatu National Council of Chiefs). This institution is an important place for the preservation and promotion of the different aspects of the local culture. Traditional artifacts from several islands are on display in the museum. The centre host also the National Audiovisual Archives which is the most important fund of documents from the late 19th century until today.

Port Vila was the location in August 1999 for the "2nd World Heritage Global Strategy Meeting for the Pacific Islands Region" held by UNESCO.
