Strathearn or Strath Earn (/stræθˈɜːrn/), also the Earn Valley, is the strath of the River Earn, which flows from Loch Earn to meet the River Tay in the east of Scotland.
The area covers the 30 mile stretch of the river, containing a number of settlements in Perthshire.[1] It shares a name with a modern ward used for elections to Perth and Kinross Council.
Strathearn was also the name of a ancient province of the Kingdom of Alba,[2] under the authority of a mormaer and then an Earl. More recently, the name has since been used in a number of titles used by the British Royal Family.
