Lanzarote (UK: , Spanish: [lanθaˈɾote], locally [lansaˈɾote]) is a Spanish island, the easternmost of the Canary Islands in the Atlantic Ocean. It is located approximately 125 kilometres (80 miles) off the north coast of Africa and 1,000 kilometres (600 miles) from the Iberian Peninsula. Covering 845.94 square kilometres (326.62 square miles), Lanzarote is the fourth-largest of the islands in the archipelago. With 152,289 inhabitants at the start of 2019, it is the third most populous Canary Island, after Tenerife and Gran Canaria. Located in the centre-west of the island is Timanfaya National Park, one of its main attractions. The island was declared a biosphere reserve by UNESCO in 1993. The island's capital is Arrecife, which lies on the eastern coastline. It is the smaller main island of the Province of Las Palmas.

The first recorded name for the island, given by Italian-Majorcan cartographer Angelino Dulcert, was Insula de Lanzarotus Marocelus, after the Genoese navigator Lancelotto Malocello, from which the modern name is derived. The island's name in the native Guanche language was Tyterogaka or Tytheroygaka, which may mean "one that is all ochre" (referring to the island's predominant colour).
