Sir Louis Henry Davies KCMG PC (May 4, 1845 – May 1, 1924) was a Canadian lawyer, businessman and politician, and judge from the province of Prince Edward Island.

[citation needed] In 1877, Davies was one of the Canadian counsel who appeared on behalf of the British Government before the Halifax Fisheries Commission, appointed under the Treaty of Washington (1871) to resolve outstanding issues, including fishing rights.

[4][1] Davies was first elected to the House of Assembly as a Liberal in 1872 just prior to Prince Edward Island entering Canadian confederation.

[citation needed] Davies won a seat in the House of Commons of Canada in the 1882 federal election as a Liberal.

[citation needed] When the Liberals formed government after the 1896 election under Sir Wilfrid Laurier, Davies became minister of marine and fisheries, and during 1898–1899 he was a member of the Anglo-American joint high commission at Quebec.

[citation needed] The Prince Edward Island Supreme Court building in Charlottetown is named in his honour.
