The Bogle–Chandler case refers to the mysterious deaths of Dr. Gilbert Bogle and Margaret Chandler on the banks of the Lane Cove River in Sydney, Australia on 1 January 1963. The case became famous because of the circumstances in which the bodies were found and because the cause of death could not be established.

In 2006, Peter Butt, a filmmaker, discovered evidence to suggest the cause of death was hydrogen sulphide (H

S
) gas. In the early hours of 1 January, an eruption of gas from the polluted river bed may have occurred, causing the noxious fumes to pool in deadly quantities in the grove.
