State election for New South Wales, Australia in October 1927
The 1927 New South Wales state election to elect the 90 members of the 28th Legislative Assembly was held on 8 October 1927. During the previous parliament the voting system, Single transferable voting, a form of proportional representation with multi-member seats (modified Hare-Clark), had been changed to single member constituencies and Instant-runoff voting (optional preferential voting). 
Severe divisions occurred within the Labor Party caucus in the four months prior to the election (see Lang Labor). A caretaker government composed of the supporters of the Premier of New South Wales and party leader, Jack Lang was in power at the time of the election.
As a result of the election the Lang government was defeated and a Nationalist/Country Party coalition government led by Thomas Bavin and Ernest Buttenshaw was formed with a parliamentary majority of 1 and the usual support of the 2 Nationalist independents. The Parliament first met on 3 November 1927, and ran its maximum term of 3 years. Lang remained the leader of the Labor Party throughout the Parliament.
To date Lang is the only elected Labor Premier of New South Wales to be voted out of office.
Subsequent Labor Premiers who has lost office were all non-elected.
