An election to the County Council of London took place on 5 March 1910. It was the eighth triennial election of the whole Council. The size of the council was 118 councillors and 19 aldermen. The councillors were elected for electoral divisions corresponding to the parliamentary constituencies that had been created by the Representation of the People Act 1884. There were 57 dual member constituencies and one four member constituency. The council was elected by First Past the Post with each elector having two votes in the dual member seats.

The London County Council (LCC) was the principal local government body for the County of London throughout its existence from 1889 to 1965, and the first London-wide general municipal authority to be directly elected. It covered the area today known as Inner London and was replaced by the Greater London Council. The LCC was the largest, most significant and most ambitious English municipal authority of its day.
