Sir William Scott, Lord Clerkington (died 1656) was a Scottish politician and judge.
Scott owned Malleny House and Garden which later passed to several generations of his descendants via his son John.
Due to the enactment of the act of classes, which made it impossible for those who took part in the engagement on behalf of Charles I to hold office, Scott was in June 1649 appointed an ordinary lord of session with the title of Lord Clerkington.
He was also one of the committee of estates, and took a prominent part in affairs at the period of Charles II's recall to Scotland in June 1650.
[3] Scott had one son, Laurence; and by his second wife, Barbara, daughter of Sir John Dalmahoy of Dalmahoy, bart., he had three sons and three daughters.
