The 1987 New Brunswick general election was held on October 13, 1987, to elect 58 members to the 51st New Brunswick Legislative Assembly, the governing house of the province of New Brunswick, Canada. The Liberal Party won power for the first time since 1967. They did so in a landslide, winning all 58 seats in the legislature. This feat was only accomplished one other time in Canadian history, in the 1935 Prince Edward Island election.

The 1935 Prince Edward Island general election was held in the Canadian province of Prince Edward Island on 23 July 1935. The Liberal Party led by Walter Lea swept the board by winning every seat in every constituency. This was the first time that a government in the British Commonwealth would face no opposition in an elected chamber. To date, this feat has only been accomplished one other time in Canadian history, the 1987 New Brunswick election.
