Parliamentary elections were held in Nauru on 6 December 1986. As there were no political parties, all candidates ran as independents. However, the Parliament elected had two opposing groups holding nine seats each, resulting in a deadlock. To resolve the issue, Parliament was dissolved on 30 December, prompting fresh elections in January.
The 1986 election was notable in that, for the first time ever, a female candidate was elected. Ruby Dediya was elected MP for Anetan / Ewa, and was appointed Minister for Finance. She retained the position after the 1987 election.
