Duke of Clarence and Avondale was a title awarded to Prince Albert Victor, a grandson of Queen Victoria, in the Peerage of the United Kingdom.
'Clarence' is believed to refer to Clare in Suffolk; 'Avondale' refers to the valley of the Avon Water in Scotland.
Whilst there had previously been several creations of Dukes of Clarence (and one Duke of Clarence and St Andrews), the sole creation of a dukedom of Clarence and Avondale was for Albert Victor, the eldest son of the Prince of Wales (later King Edward VII). This was the last royal dukedom to be created with two territorial designations.
The Duke died of pneumonia in 1892 before his planned marriage so the title became extinct. He is buried in the Albert Memorial Chapel adjoining St George's Chapel, Windsor, beneath an Art Nouveau memorial designed by Sir Alfred Gilbert.
