Port of Arica, Maritime port in Arica, Chile

The Port of Arica is a port on the Pacific coast of northern Chile. Within it, the Peruvian pier (MASP Arica) is a direct-berth pier 214.7 m long and 57.9 m wide, with a 2,077 m² warehouse and a 21,740 m² open operating area. Its SE-NW orientation gives a depth of 10 m and a maximum vessel length of 160 m.

The pier Peru operates in Arica derives from the 1929 Treaty of Lima, which granted Peru a berth and other servitudes in the Chilean port while Chile kept sovereignty. On 7 March 2000, ministers Fernando de Trazegnies and Gabriel Valdés inaugurated the Cristo de la Concordia in Arica and Chile handed over the facilities covered by the treaty. The adjacent Tacna–Arica railway was built in 1856 by the British firm The Arica & Tacna Railway Co.

The port serves as a vital trade connection between Chile and Bolivia, shaping economic life in the region through daily maritime activities. Local communities view this facility as essential to their livelihoods and regional commerce.

The port requires experienced pilots for all vessels and provides maintenance facilities, fuel, and communication equipment for operations. Visitors should note this is an active working facility with limited public access to most areas.

The pier is berth 7 in sector 3 of Arica Bay, a 214.7 m long and 57.9 m wide finger pier with a 10 m draft and a 2,077 m² warehouse. Peru operates it under the 1929 Treaty of Lima, with its own migration, customs and labour authority; in 2005 it handled 33 large vessels and 2,163 containers.
