2017 East Lothian Council election

2017 Elections to East Lothian Council were held on 4 May 2017 on the same day as the other Scottish local government elections. The election consisted of 6 wards electing three or four councillors using the single transferable vote system form of proportional representation, with 22 councillors elected.

This election featured revised ward boundaries to three wards resulting in the reduction of the number of East Lothian councillors from 23 to 22. Two former Musselburgh wards were merged, while losing Wallyford and Whitecraig with 4 councillors being elected. The bulk of the previous Fa'side ward became Tranent/Wallyford/Macmerry. Haddington and Lammermuir ward expanded with the addition of Ormiston and Pencaitland and gained a councillor.

Following the elections, Labour announced that they would form a minority administration. This replaced the previous coalition between Labour, the Conservatives and the one Independent councillor.
