Haddingtonshire County Council was created in 1890 under the [[Local Government (Scotland) Act 1889]], which established elected county councils across Scotland, taking over most of the functions of the [[Commissioners of Supply]], which had been the main administrative body of the shire since 1667. The county council was based at [[County Buildings, Haddington|County Buildings]] in Court Street, Haddington, which had been built in 1833 and also served as the county's [[sheriff court]].<ref>{{Historic Environment Scotland|num= LB34260|desc= Haddington County Buildings including rear wings and former villa at 27 Court Street and excluding flat roofed block to southeast and pitched quadrangle to south (John Muir House), Court Street, Haddington|fewer-links=yes|access-date=18 July 2021}}</ref>

In April 1921 the county council voted to request a change of the county's name from Haddingtonshire to "East Lothian".<ref>{{cite news |title=Border news in brief |url=https://www.britishnewspaperarchive.co.uk/ |access-date=21 December 2022 |work=Southern Reporter |date=7 April 1921 |location=Selkirk |page=6 |quote=It was agreed at a special meeting of Haddington County Council on Friday [1 April 1921], on the motion of Lord Polwarth, to apply for a Provisional Order to vest Haddington County Buildings in the Council, and to change the designation of the county from "Haddington" to "East Lothian".}}</ref> The government agreed and brought the change into effect as part of the East Lothian County Buildings Order Confirmation Act 1921, which received [[royal assent]] on 8 November 1921. The act also transferred ownership of the County Buildings to the county council.<ref>{{cite news |title=East Lothian Order |url=https://www.britishnewspaperarchive.co.uk/ |access-date=21 December 2022 |work=The Scotsman |date=25 April 1921 |location=Edinburgh |page=10}}</ref><ref>{{London Gazette|issue=13760|page=1950|date=15 November 1921|city=e}}</ref><ref>{{cite web|url=https://www.legislation.gov.uk/ukla/Geo5/11-12/123/pdfs/ukla_19210123_en.pdf|title=East Lothian County Buildings Order Confirmation Act 1921|publisher=[[The National Archives (United Kingdom)|The National Archives]]|accessdate=10 November 2023}}</ref>

In 1975 under the [[Local Government (Scotland) Act 1973]], Scotland's county councils were dissolved and a new system of regional and district councils was created. East Lothian [[Regions and districts of Scotland|District]] was created within the wider [[Lothian]] [[Regions and districts of Scotland|region]]. The district comprised the historic county of East Lothian plus the burgh of Musselburgh and the parish of [[Inveresk]] (which included [[Wallyford]] and [[Whitecraig]]) from the county of Midlothian.

When further reforms in 1996 moved Scotland to a system of 32 unitary local authorities, the modern council area of East Lothian was created.
