Lothian East (/ˈlðiən/; Scots: Lowden East; Scottish Gaelic: Lodainn an Ear) is a constituency in Scotland which returns one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first-past-the-post voting system. The seat has been represented since 2024 by Douglas Alexander of Scottish Labour; he had previously been MP for Paisley and Renfrewshire South, formerly Paisley South, from 1997 to 2015.

The constituency was formerly known as East Lothian. It was renamed as a result of the 2023 review of Westminster constituencies and was first contested under the new name at the 2024 general election.
