Parliamentary elections were held in Sierra Leone on 6 May 1977.
Elections were called ahead of schedule by president Siaka Stevens following his declaration of a state of emergency after student riots earlier in the year.
In a campaign marred by violence, elections in eight constituencies were not held on the day of the election, but were contested at a later date.
The following year, a referendum approved a new constitution that made the country a one-party state with the APC as the sole legal party.
Another referendum in 1991 returned the country to multi-party politics, and the next pluriform elections were held in 1996.
