Tacna

San Pedro de Tacna (English: Saint Peter of Tacna), or simply Tacna, is a city in southern Peru and the regional capital of the Tacna Region. It is located on the border with Chile, inland from the Pacific Ocean and in the valley of the Caplina River. Tacna is a very commercially active city, located only 35 km (22 mi) north of the border with Chile.

Initially called San Pedro de Tacna, it has gained a reputation for patriotism, with many monuments and streets named after heroes of Peru's struggle for independence (1821–1824) and the War of the Pacific (1879–1883). Residents of Tacna are known in Spanish as tacneños.
