Sir Richard William Scott, PC KC (February 24, 1825 – April 23, 1913) was a Canadian politician and cabinet minister.

Scott became a member of municipal council in 1851, was mayor of Bytown in 1852, and held a seat in the Legislative Assembly of the Province of Canada from 1857 to 1863.

In November 1873, he left provincial politics when he was appointed minister without portfolio by Alexander Mackenzie in the federal Cabinet.

Mackenzie had become prime minister after Sir John A. Macdonald's government had been forced to resign because of the Pacific Scandal.

A supporter of temperance, he drafted the "Scott Act," which allowed any county or municipality in Canada to prohibit the retail sale of liquor by majority vote.
