Maldivian constitutional referendum, 1968

A constitutional referendum was held in the Maldives on 15 March 1968. The main question was whether to convert the state from a constitutional monarchy under Sultan Muhammad Fareed Didi, to a presidential system. The referendum was the third on the subject; the first in 1952 had seen the state convert to a presidential system, whilst a second in 1953 reversed the decision and saw the monarchy restored in 1954.

The proposals were approved by over 80% of voters, and a republic was declared on 11 November that year. Prime Minister Ibrahim Nasir becoming president.
