The 1996 Blaxland by-election was held in the Australian electorate of Blaxland in New South Wales on 15 June 1996. The by-election was triggered by the resignation of the sitting member, the Australian Labor Party's Paul Keating on 23 April 1996. The writ for the by-election was issued on 13 May 1996.
Blaxland had been held since 1969 by Paul Keating, who had been Treasurer under Bob Hawke from 1983, until he defeated Hawke in a leadership challenge in December 1991, becoming Prime Minister of Australia. Keating went on to defeat John Hewson at the 1993 election, but three years later the ALP was defeated in a landslide victory by a resurgent Coalition led by John Howard at the 1996 election on 2 March. Following the party's election loss, Keating immediately resigned as party leader, and several weeks later, resigned from the Parliament.

On a two-party preferred basis, RARI gained their best ever result in an election, gaining over 30% of the vote on preferences.
