La Paz (Spanish: [la ˈpas]; lit. 'the peace'), officially Nuestra Señora de La Paz (Aymara: Chuqi Yapu Aymara pronunciation: [ˈtʃoqɛ ˈjapʊ]), is the seat of government of Bolivia. With 755,732 residents as of 2024, it is the third-most populous city in Bolivia. Its metropolitan area, which includes the neighboring city of El Alto, and other smaller towns, is the second most populous urban area in Bolivia, with a population of 2.2 million, after Santa Cruz de la Sierra with a population of 2.3 million.

Located in west-central Bolivia 68 km (42 mi) southeast of Lake Titicaca, La Paz is set in a canyon created by the Choqueyapu River. It is in a bowl-like depression, part of the Amazon basin, surrounded by the high mountains of the Altiplano. Overlooking the city is the triple-peaked Illimani. Its peaks are always snow-covered and can be seen from many parts of the city. At an elevation of roughly 3,650 m (11,975 ft) above sea level, La Paz is the highest administrative capital city in the world. Due to its altitude, the city has an unusual subtropical highland climate, with rainy summers and dry winters.
