The 1930 East Renfrewshire by-election was a parliamentary by-election held on 28 November 1930 for the British House of Commons constituency of East Renfrewshire in Scotland.
On a slightly-reduced turnout, the result was a victory for The Marquess of Clydesdale, who won 54% of the votes. He was re-elected at the next two general elections, remaining East Renfrewshire's MP until he succeeded to the Dukedom in 1940, triggering another by-election. == Votes ==
