General elections were held in Saint Kitts-Nevis-Anguilla on 25 July 1966. The result was a victory for the Saint Kitts-Nevis-Anguilla Labour Party, which won seven of the ten seats. Voter turnout was 70%.
The elections were the first that the People's Action Movement (PAM) contested, having been founded the year before.
The elections saw large differences in support across the three islands; in St Kitts, Labour received 65% of the vote and won all seven seats; however they did not win any seats outside of St Kitts: In Anguilla the PAM received 54% of the vote and won its only seat, while they also dominated in Nevis, where they received 52% of the vote and won one of the island's two seats, with the Nevis-based United National Movement winning the second.
