The 2017 Midlothian Council election took place on 4 May 2017 to elect members of Midlothian Council. The election used the six wards created as a result of the Local Governance (Scotland) Act 2004, with each ward electing three Councillors using the single transferable vote system form of proportional representation, with 18 Councillors being elected.
It was the first time that the Conservative party had won council seats in Midlothian since the 1995 election.
Note: "Votes" are the first preference votes. The net gain/loss and percentage changes relate to the result of the previous Scottish local elections on 3 May 2007. This may differ from other published sources showing gain/loss relative to seats held at dissolution of Scotland's councils.
