Morro de Arica is a steep hill located in the Chilean city of Arica. Its height is 139 metres above sea level. It was the last bulwark of defence for the Peruvian troops who garrisoned the city during the War of the Pacific (1879–1883). Morro de Arica was assaulted and captured on June 7, 1880 by Chilean troops in the last part of the Tacna and Arica campaign.
