Elections to Comhairle nan Eilean Siar (Scottish Gaelic for 'Council of the Western Isles') took place on 5 May 2022 on the same day as the 31 other Scottish local government elections. The election will be the first to use the nine wards created under the Islands (Scotland) Act 2018 which allowed for single and dual member wards, with 29 councillors being elected. Each ward elected either 2, 3 or 4 members, using the Single Transferrable Vote electoral system, a form of proportional representation. Following a boundary review the number of wards will increase from nine to 11 while the number of councillors elected will fall from 31 to 29.
