Scotland will have a referee at the Six Nations for first time in 19 years after Mike Adamson was chosen to officiate at the 2021 tournament.
The 36-year-old from Stirling will take charge of England v Italy at Twickenham on 13 February.
A former Sevens international, Adamson will be an assistant referee in three further fixtures.
"Getting an appointment like this feels similar to being a player selected for the team," he said.
"It's a great feeling, but then you need to put in a good performance. It's the same in refereeing, I need to do a good job."
