The Álvaro de Bazán (F101) is the lead ship of the Álvaro de Bazán class of air defence frigates entering service with the Spanish Navy. She is named after Admiral Álvaro de Bazán.
In late 2005, Álvaro de Bazán was deployed as part of the USS Theodore Roosevelt aircraft carrier battle group in the Persian Gulf. This was the first deployment of a Spanish warship as part of an American naval battle group.
In early March 2007, the Álvaro de Bazán was the first Spanish Naval Vessel to visit Australia in 150 years. The ship made several port visits around Australia in conjunction with the Spanish Naval ship builder Navantia's bid to design the Royal Australian Navy's new Air Warfare Destroyer. The ship was also visiting Australia as part of the first circumnavigation of the globe by a Spanish warship in 142 years.
