John Mercer Johnson (October 1818 – November 8, 1868) was a Canadian lawyer and politician from the Province of New Brunswick, and a Father of Confederation. He represented Northumberland in the Legislative Assembly of New Brunswick from 1850 to 1865, and again from 1866 to 1867, each time elected as a candidate aligned with the liberal movement. Johnson was appointed to the Executive Council of New Brunswick and became the province's solicitor general, postmaster, minister without portfolio and attorney general. He attended all three conferences for Canadian Confederation and supported Canada's creation. In the first parliament for the country of Canada, Johnson was elected to represent Northumberland, serving in the role from 1867 to 1868 as a Liberal member. Plaques have been erected in his honour in Chatham, his hometown, and a mountain in Northumberland county was named for him.
