The Movement for National Unity was a political party in Saint Vincent and the Grenadines. It was formed shortly before the 1984 general elections by a split from the United People's Movement due to the refusal of most party members to disown Fidel Castro's politics. The new party received 2.0% of the vote, but failed to win a seat. In the 1989 elections it increased its share of the vote to 2.4%, but remained seatless. However, in the 1994 elections it received 17.4% of the vote and won a single seat. In the same year it merged with the Saint Vincent Labour Party to form the Unity Labour Party.
