Kenneth Alexander Blatchford (March 5, 1882 – April 20, 1933) was a Canadian politician who served as both mayor of Edmonton, Alberta and a member of the House of Commons of Canada.

He resigned midway through his term to run for mayor in the 1923 election, in which he handily defeated James Ramsey.

After his federal political career faltered, Blatchford attempted a return to municipal office by running for mayor in the 1932 election.

While still mayor, Blatchford ran for the House of Commons of Canada in the 1926 election as a Liberal in Edmonton East.

His son, Howard Peter "Cowboy" Blatchford went on to become a flying ace in the Royal Canadian Air Force during the Second World War.
