A constitutional referendum was held in Chile on 30 July 1989 to approve a series of amendments to the 1980 Constitution. The proposed changes were overwhelmingly supported, with 91% of voters in favor.

Background

Following the defeat of General Augusto Pinochet in the 1988 plebiscite, where Chileans voted against extending his rule, Pinochet and opposition forces agreed to revise the 1980 Constitution. The referendum sought to implement 54 constitutional reforms. Key amendments included changes to the procedures for amending the Constitution, limitations on emergency powers, recognition of political pluralism, and the strengthening of constitutional rights and democratic principles, including broader participation in political life. The government and nearly all political parties supported the reforms. However, the right-wing Party of the South and the Chilean Socialist Party (not to be confused with the Socialist Party of Chile) opposed the changes, advocating for a "No" vote.
