This article is the Electoral history of Sir John Sparrow David Thompson, the fourth Prime Minister of Canada. A Conservative, he became prime minister upon the resignation of Prime Minister Sir John Abbott in 1892. Thompson served a short term of just over two years as prime minister (1892–1894), until he died suddenly in office and was succeeded by Sir Mackenzie Bowell. He never led his party in a general election.
Before entering federal politics, Thompson was a member of the General Assembly of Nova Scotia from 1877 to 1882. He was the Attorney General for Nova Scotia from 1878 to 1882 and was briefly the Premier of Nova Scotia in the run-up to the general election of 1882.
