On 25 September 1998 a catastrophic fire occurred at the Esso natural gas plant in Longford, Victoria, Australia. A pressure vessel ruptured resulting in a serious jet fire, which escalated to a conflagration extending to a large part of the plant. Fires lasted two days before they were finally extinguished.

Two workers were killed and eight others injured. Natural gas supply to the state of Victoria was severely disrupted and was not fully restored until 14 October. Total estimated property costs amounted to US$443 million (US$987 million in 2021), while financial losses to the companies affected by the gas shortage were estimated at around A$1.3 billion.

The Victorian state government established the Longford Royal Commission to publicly investigate the causes of the accident.
