A by-election was held for the Australian House of Representatives seat of Adelaide on 6 February 1988. This was triggered by the resignation of Labor Party MP Chris Hurford to become Australia's Consul-General in New York City.
The election was won by Liberal candidate Mike Pratt with an 8.4 percent two-party swing on a 1.9 percent margin, defeating Labor candidate Don Farrell.
The 1988 Port Adelaide by-election occurred seven weeks later.
