The 25th 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, Cartiere del Timavo, 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.
Analysts had wondered why Robichaud decided to call the election only two and a half years into his mandate over what they thought was a small issue. Several of his projects, such as tax reform and an overhaul of post-secondary education (which eventually led to the creation of the Université de Moncton and the University of New Brunswick at Saint John), died in the legislature. However, Robichaud later said that he held the election when his popularity was at its height and the Conservatives were weak.
Robichaud campaigned on a platform of economic development and encouragement of outside investment in the province. Cartiere del Timavo threatened to cancel the project if the Liberals lost the election. Many voters perceived Sherwood as too timid in his attacks on the Liberals on the campaign trail, as compared to his vigorous speeches in the Legislature.
