Coalite is a brand of low-temperature coke used as a smokeless fuel. The title refers to the residue left behind when coal is carbonised at 640 degrees Celsius. It was invented by Thomas Parker in 1904. In 1936 the Smoke Abatement Society awarded its inventor a posthumous gold medal.

Coalite is darker and more friable than high temperature coke. It is easier to ignite, burns with an attractive flame, and is lighter than coal, making it an ideal fuel for open domestic firegrates. Drawbacks are its tendencies to produce an excessive residual ash, to burn quickly and give off sulphurous fumes.
