John James Fraser (August 1, 1829 – November 24, 1896) was a New Brunswick (Canada) lawyer, judge, and politician.

That year he won a seat in the legislature and served as Provincial Secretary from 1872 to 1878 when he succeeded George E. King as Premier and Attorney-General.

Fraser was the first premier to give both the Acadian and the Irish sections of the Roman Catholic community effective representation in cabinet.

Pierre-Amand Landry was made commissioner of public works, while Michael Adams became a surveyor-general with responsibility for administering crown lands.

In 1882, after running unsuccessfully for a seat in the federal parliament, Fraser left politics and was appointed to the provincial supreme court and from 1893 to 1896 he served as the ninth Lieutenant Governor of the province.
