The National Portrait Gallery (Swedish: Statens porträttsamling) at the Gripsholm Castle in Mariefred is a collection of portraits of prominent Swedes. The National Portrait Gallery acquired the status of a national portrait gallery during Gustav III's time.
The National Portrait Gallery was officially founded in 1822 with over 4000 works that trace the portrait art changes from the 1500s to the present. Nationalmuseum has been responsible for the portrait collection since 1860. This arrangement has been periodically extended.
