Agnetha Fältskog (Swedish pronunciation: [aŋˈneː.ˈta ˈfɛlt.ˈskuːɡ], born 5 April 1950) is a Swedish recording artist. She achieved success in Sweden after the release of her debut album Agnetha Fältskog in 1968, and reached international stardom as a member of the pop group ABBA, which has sold over 370 million albums and singles worldwide, making them one of the best-selling music artists in history and the second or third best-selling band in history.

Since the break-up of ABBA, Fältskog has continued to have success as a solo artist, albeit interspersed by periods of relative recording inactivity.
