List of members of London County Council 1889–1919

This is a list of councillors and aldermen elected or co-opted to the London County Council from its creation under the Local Government Act 1888 until 1919.

Elections resumed in 1919 under new electoral boundaries and are detailed in List of members of London County Council 1919–37.

The divisions were identical to the constituencies for elections to the United Kingdom House of Commons that had been created by the Redistribution of Seats Act 1885.

In 1906 the Moderate grouping was reorganised as the Municipal Reform Party and as such gained a majority and control of the Council in the 1907 elections.

The Elections and Registration Act 1915 gave the council the power to co-opt members to fill casual vacancies.

The first women who could clearly serve as members were elected as councillors (and as an alderman) in 1910 (Henrietta Adler, Susan Lawrence and Lady St Helier).
