Parliamentary elections were held in Romania on 17 March 1985. The Front of Socialist Unity, dominated by the Romanian Communist Party and including other mass organisations, was the only organisation that contested the election. No prospective candidate could run for office without the Front's approval. The Front won all 369 seats in the Great National Assembly. These would be the last single-party elections held in Romania; the Communists would be overthrown four years later.

Candidates were elected in single member constituencies, and had to receive over 50% of the vote. If no candidate passed this threshold, or if voter turnout in the constituency was less than 50%, re-runs were held until the requirements were met. Voters had the option of voting against the Front candidates.
