The 1963 New Brunswick general election was held on April 22, 1963, to elect 52 members to the 45th New Brunswick Legislative Assembly, the governing house of the province of New Brunswick, Canada. The election was called by surprise by Liberal Premier Louis Robichaud. The Progressive Conservatives, under leader Cy Sherwood, had accused the Liberals of corruption for allowing an Italian company, , to construct a paper mill in Newcastle, and grant it rights to Crown land over other companies. The Tories also claimed that Lieutenant-Governor Leonard O'Brien had sold land to the company. Robichaud made a quick decision to call an election amidst these accusations.
