Robinson Souttar (23 October 1848 – 4 April 1912) was a British Liberal Party politician. He first stood for Parliament at the 1892 general election, when he was an unsuccessful candidate in the Conservative-held Oxford seat. He was elected at the 1895 general election as the member of parliament (MP) for Dumfriesshire, defeating the sitting Liberal Unionist MP William Maxwell by a majority of only 13 votes. Maxwell regained the seat in 1900, and Souttar did not stand again.
