The Telefónica Building, in Spanish Edificio Telefónica, is a skyscraper in Madrid, Spain. It is located in Gran Via 28. At the time of construction it was the tallest European skyscraper with 89 m of roof height, until in 1940, when the Terrazza Martini Tower opened in Genoa.

A skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
