Tacna, officially known as San Pedro de Tacna, is a city in southern Peru and the regional capital of the Tacna Region. A very commercially active city, it is located only 35 km (22 mi) north of the border with Arica y Parinacota Region from Chile, inland from the Pacific Ocean and in the valley of the Caplina River. It is Peru's tenth most populous city.

The city has gained a reputation for its 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.
