Peter Fisher (9 June 1782 – 15 August 1848) was a historian and merchant in the British colony of New Brunswick.
He was the son of United Empire Loyalist refugees of the American Revolutionary War who fled north in 1783.
Fisher's family settled at St. Anne's Point on the Saint John River, which was an area set aside for the Loyalist military regiments.
St. Anne's Point was later renamed Fredericton and designated the capital of the newly established colony.
Other works may be his, however, an apparent unwillingness to claim authorship on his part has made authentication difficult.
