Movistar (Spanish pronunciation: [moβisˈtaɾ]) is a Spanish major telecommunications provider owned by Telefónica, operating in Spain and Hispanic American countries. It is the largest provider of landline, broadband, mobile services, and pay television (Movistar Plus+) in Spain. Movistar is the second-largest wireless carrier in Mexico, with 25.8 million subscribers as of January 2020.
The Movistar brand has been in use in Spain since the launch of GSM services in 1995. The name became effective worldwide on April 5, 2005, after Telefónica purchased the BellSouth mobile operations branch in South America. After the purchase of O2 in 2005 by Telefónica, the company announced that the «O2» brand would continue to be used in the United Kingdom and Germany, as a separate branch with its own board and management structure. Since 2011, Telefónica has sponsored a UCI ProTeam squad in cycling under the name of Movistar Team.
Since 2019, Telefónica has decided to divest all of Movistar's operations in Latin America, with Venezuela being the only country in Latin America who has Movistar and being directly owned by Telefónica (Movistar México is owned by a third-party company who continues to use the Movistar name under a license agreement, and Brazil uses the Vivo brand instead of Movistar).

The 1983 song "Walking on Sunshine" by Katrina and the Waves was used by Telefónica to announce the unification of all its operation brands (Telefónica MoviStar, Bellsouth, Unifon, Telefónica Moviles, Telefónica Movil, and Movicom) in Latin America and Spain under the Movistar brand after the takeover of BellSouth's Latin America division. Movistar has also used the New Radicals' hit "You Get What You Give" and "Two Princes" by Spin Doctors. Currently "Hey, Soul Sister" by Train is in advertising and other versions of the song are also used in audiovisual advertisements.
