Anstruther Easter in Fife was a royal burgh, created in 1583, that returned one commissioner to the Parliament of Scotland and to the Convention of Estates.
After the Acts of Union 1707, Anstruther Easter, Anstruther Wester, Crail, Kilrenny and Pittenweem formed the Anstruther Easter district of burghs, returning one member between them to the House of Commons of Great Britain.
