Salvador (Portuguese pronunciation: [sawvaˈdoʁ], Saviour; historic name: Cidade de São Salvador da Bahia de Todos os Santos, in English: "City of the Holy Saviour of the Bay of all Saints") is the largest city on the northeast coast of Brazil and the capital of the Northeastern Brazilian state of Bahia. Salvador is also known as Brazil's capital of happiness due to its easygoing population and countless popular outdoor parties, including its street carnival. The first colonial capital of Brazil, the city is one of the oldest in the Americas. For a long time, it was simply known as Bahia, and appears under that name (or as Salvador da Bahia, Salvador of Bahia so as to differentiate it from other Brazilian cities of the same name) on many maps and books from before the mid-20th century. Salvador is the third most populous Brazilian city, after São Paulo and Rio de Janeiro.

The city of Salvador is notable in Brazil for its cuisine, music and architecture, and its metropolitan area is the wealthiest in Brazil's Northeast. The African influence in many cultural aspects of the city makes it the center of Afro-Brazilian culture. This reflects a situation in which African-associated cultural practices are celebrated. The historical center of Salvador, frequently called the Pelourinho, is renowned for its Portuguese colonial architecture with historical monuments dating from the 17th through the 19th centuries and was declared a World Heritage Site by UNESCO in 1985.

Bahia (local pronunciation: [baˈi.ɐ]) is one of the 26 states of Brazil, and is located in the northeastern part of the country on the Atlantic coast. It is the fourth most populous Brazilian state after São Paulo, Minas Gerais and Rio de Janeiro, and the fifth-largest in size. Bahia's capital is the city of Salvador, or more properly, São Salvador da Bahia de Todos os Santos, and is located at the junction of the Atlantic Ocean and the Bay of All Saints, first seen by European sailors in 1501. The name "bahia" is an archaic spelling of the Portuguese word baía, meaning "bay".

The state's geographical regions comprise the Atlantic Forest. The Recôncavo region radiating from the Bay (the largest in Brazil), the site of sugar and tobacco cultivation. And the Planalto, which includes the fabled sertão region of Bahia's far interior. Bahia is bordered, in counterclockwise fashion, by Sergipe, Alagoas, Pernambuco and Piauí to the north, Goiás and Tocantins to the west, and Minas Gerais and Espírito Santo to the south. The State of Bahia is crossed from north to south by a mountain chain which is marked, in the map, as Chapada Diamantina. This same chain receives other names, like Serra do Espinhaço, in Minas Gerais, and Borborema, in Pernambuco and Paraíba.
