Elections to the 49th Parliament of New South Wales were held on Saturday 19 March 1988. All seats in the Legislative Assembly and a third of the seats in the Legislative Council were up for election. The Labor government of Premier Barrie Unsworth was defeated by the Liberal-National Coalition, led by Opposition Leader Nick Greiner. The election took place following a redistribution of seats, which resulted in the Assembly growing from 99 to 109 seats.
