San Marcos de Arica

San Marcos de Arica has managed the trick in three different decades: 1981, 2012, 2014. The first of those came in the club's formative years and arrived alongside the Copa Apertura Segunda División the same season, then a Copa Campeones the year after, in 1982. Primera B wins in 2012 and 2014, a Tercera División title in 2007, and, once the Chilean league pyramid was restructured, the Segunda División Profesional crown in 2019.

Founded on 14 February 1978, the club carries the nickname Los Bravos del Morro . Home matches are played at Estadio Carlos Dittborn, reduced to 9,746 seats after a 2013–14 rebuild. Light blue shirts over blue shorts were the traditional kit, chosen to echo the Arica sky and the Morro itself, though orange has been the shirt colour worn more often since 2019.
