El Río (Spanish: Estrecho del Río) is the name given to the sea strait that separates La Graciosa from Lanzarote in the Canary Islands. Río, in Spanish, means 'river'. At its narrowest point, the strait is just over 1.1 kilometres (0.68 mi; 0.59 nmi) wide.
El Río is part of the marine reserve established around La Graciosa and the islets north of Lanzarote.
Graciosa Island or commonly La Graciosa (Spanish: [la ɣɾaˈθjosa] ; locally [la ɣɾaˈsjosa] Spanish for "the graceful") is a volcanic island in the Canary Islands of Spain, located two kilometres (one nautical mile) north of Lanzarote across the Strait of El Río. As the rest of the Canary Islands, it was formed by the Canary hotspot. The island is part of the Chinijo Archipelago and the Chinijo Archipelago Natural Park (Parque Natural del Archipiélago Chinijo). It is administered by the municipality of Teguise in the neighboring island of Lanzarote. In 2018 La Graciosa was officially declared the eighth Canary Island by the Spanish Senate, with few real effects. Before then, the island had the status of an islet. It is administratively dependent on the island of Lanzarote.
The only two settlements on the island are Caleta de Sebo in the southeastern part of the island and summer-residence Casas de Pedro Barba; the rest of the island is owned by the Government of Spain and is administered by the National Parks Autonomous Agency.
