A by-election for the seat of Newcastle in the New South Wales Legislative Assembly was held on 25 October 2014. The by-election was triggered by the resignation of Liberal-turned-independent MP Tim Owen, who won the seat at the 2011 election with a 36.7 percent primary and 52.6 percent two-party-preferred vote. The previous New South Wales by-election had seen a 26-point two-party-preferred swing to Labor.
