Triana is a neighbourhood and administrative district on the west bank of the Guadalquivir River in the city of Seville, Spain. Like other neighborhoods that were historically separated from the main city, it was known as an arrabal. Triana is located on a peninsula between two branches of the Guadalquivir, narrowly linked to the mainland in the north. Two other districts are also usually included in this area, Los Remedios to the south and La Cartuja to the north.

Residents of Triana have traditionally been called trianeros; they identify strongly with the neighborhood and consider it different in character from the rest of Seville. Triana has a traditional pottery and tile industry, a vibrant flamenco culture, and its own festivals; it has played an important role in the development of Sevillan culture and tradition.
