John Dunn (1820 – 10 September 1860) was a British Conservative politician.
After unsuccessfully contesting Totnes at the 1859 general election,[1] Dunn was elected Conservative MP for Dartmouth at a by-election in 1859—caused by the previous election of Edward Wyndham Harrington Schenley being declared void due to bribery and corruption. He held the seat until his death in 1860.[2] [3]
