Club Deportivo Tenerife, S.A.D. is a Spanish football club based in Santa Cruz de Tenerife, Tenerife, in the Canary Islands. Founded in 1922, it currently plays in Segunda División B, holding home matches at Estadio Heliodoro Rodríguez López, with a 24,000-seat capacity.

Club Deportivo Tenerife was founded in 1912, but some documents show the existence of Sporting Club Tenerife ten years, which could have been the club's precursor. Spain's La Liga started in 1928, but the team played in regional divisions until it was promoted to Segunda División in 1953. It first reached the top flight in 1961, being immediately relegated back and, in the following 27 years, played almost exclusively in the second level, also spending three years in Tercera División and six - five in a row - in Segunda División B, the newly-created division three (in 1978).

In 1985, when Tenerife were relegated to the third division for a second time, Javier Pérez became president of the club. The side was promoted this year to the second level and, two years later, returned to the first, after winning the promotion playoff against Real Betis (4–1 on aggregate).

Tenerife ( /tɛnəˈriːf/; Spanish: [teneˈɾife]) is the largest and most populous island of the seven Canary Islands; it is also the most populated island of Spain, with a land area of 2,034.38 km² (785.47 mi2) and 908,555 inhabitants, 43% of the total population of the Canary Islands. About five million tourists visit Tenerife each year, the most of any Canary Islands. Tenerife hosts one of the world's largest carnivals and the Carnival of Santa Cruz de Tenerife is attempting to become a World Heritage Site. Tenerife is serviced by two airports, Tenerife North Airport and Tenerife South Airport, and is the tourism and economic centre of the archipelago.

Santa Cruz de Tenerife is the capital of the island and the seat of the island council (cabildo insular). The city is capital of the autonomous community of Canary Islands (shared with Las Palmas), sharing governmental institutions such as Presidency and ministries. Between the 1833 territorial division of Spain and 1927 Santa Cruz de Tenerife was the sole capital of the Canary Islands, until in 1927 a decree ordered that the capital of the Canary Islands be shared, as it remains as at present.
