An ''ignition magneto'' (also called a ''high-tension magneto'') is an older type of ignition system used in [[spark-ignition engine]]s (such as petrol engines). It uses a [[ignition magneto|magneto]] and a [[transformer]] to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage".

Used on many cars in the early 20th century, ignition magnetos were largely replaced by induction coil ignition systems. The use of ignition magnetos is now confined mainly to engines without a battery, for example in lawnmowers and chainsaws. It is also used in modern piston-engined aircraft{{citation needed|date=April 2023}} (even though a battery is present), to avoid the engine relying on an electrical system.
