East Lothian is a constituency of the House of Commons of the UK Parliament, and a constituency of the Scottish Parliament.

The current UK parliamentary constituency covers the whole of the East Lothian council area. The Scottish parliamentary constituency excludes the five wards of Musselburgh, which instead lie in Edinburgh East and Musselburgh. Before the 1983 general election, the area lay in the Berwick and East Lothian constituency.
