The Hong Kong Island West geographical constituency is one of the ten geographical constituencies in the elections for the Legislative Council of Hong Kong which elects two members of the Legislative Council using the single non-transferable vote (SNTV) system. The constituency covers Central and Western Districts and Southern District of Hong Kong Island and Islands District in the New Territories.^[3]

The constituency was created under the overhaul of the electoral system imposed by the Beijing government in 2021, replacing Central and Western District and Southern District in the Hong Kong Island constituency and Islands District in the New Territories West constituency used from 1998 to 2021. Constituencies with the same name were also created for the 1991 and 1995 elections in the late colonial period, while the 1991 constituency also elected two seats with each voter having two votes with a similar boundary.
