Kilbirnie and Beith was one of the 10 wards used to elect members of North Ayrshire Council.

The ward was created following the Fourth Statutory Reviews of Electoral Arrangements ahead of the 2007 Scottish local elections.

As a result of the Local Governance (Scotland) Act 2004, local elections in Scotland would use the single transferable vote electoral system from 2007 onwards so Kilbirnie and Beith was formed from an amalgamation of several previous first-past-the-post wards.

The review coincided with the introduction of the Scottish Elections (Reform) Act 2020 which allowed for the creation of five-member wards.

The proposals for North Ayrshire were subsequently approved by the Scottish Parliament and the ward was abolished in 2022.
