The 2018 Antillean elections occurred on November 6, 2018, for all elected seats in the United Commonwealth Senate and the House of Representatives, along with several local elections for mayors and other municipal officials. These midterm elections occurred during the middle of the second term of Federalist President Michael Abarough. The Civic Democratic Party, a unified opposition party that was established in 2017, contested seats on the federal and commonwealth level for the first time since its creation. While the Federalists retained control of both the Senate and the House, it marked the first time since 1992 that another single party posed a serious competition for House seats and since 1988 for Senate seats. The Civic Democrats gained 75 seats in the House and 4 seats in the Senate, with some of those having previously belonged to the party's predecessors (the Liberal, Reform, and Civic National Parties), but some of them were flipped from the Federalists. The election also marked the highest voter turnout for a midterm election since 1992.
The election was widely characterized as a "blue wave" election, including several Civic Democratic upset victories over Federalist incumbents. The Civic Democrats also took control of three out of four provisional commonwealth legislatures, making it the first time since the start of the democratization of the Antilles in 1983 that the Federalists did not control at least three of the four of the commonwealth legislatures.
