Dulwich by-election, 1903
- The Unionist (Conservative) candidate was Dr Frederick Rutherfoord Harris, who had previously been elected MP for Monmouth Boroughs in the 1900 general election but was disqualified the next year as a result of an election petition alleging irregularities.
- The Liberal Party candidate was Charles Masterman.
The main issue in the by-election, as with the Lewisham by-election held on the same day, was tariff reform. Harris was a supporter of Joseph Chamberlain's proposals for Imperial Preference and was supported by the Tariff Reform League. Masterman was a supporter of the Liberal party policy of Free trade. Harris's involvement in the Jameson Raid affair was raised by his opponents.
