Producer Gas is a generic term referring to:
- Wood gas : produced in a gasifier to power cars with ordinary internal combustion engines.
- Town gas : manufactured gas, originally produced from coal, for sale to consumers and municipalities.
- Syngas : used as a fuel source or as an intermediate for the production of other chemicals.

In the UK, Producer Gas, also called Suction gas, specifically means a fuel gas made from coke or other carbonaceous material. Air is passed over the red-hot carbonaceous fuel and carbon monoxide is produced. The reaction is exothermic and proceeds as follows:
2C + O2 → 2CO
The nitrogen in the air remains unchanged, and dilutes the gas, so it has a very low calorific value. After "scrubbing", to remove tar, the gas may be used to power gas turbines which are well-suited to fuels of low calorific value.
Producer gas is a useful gas but requires careful handling because of the risk of Carbon monoxide poisoning.
