Reliant was a British car manufacturer. The company was traditionally based at Tamworth in Staffordshire.

Reliant was mainly known for producing the 3-wheeled Reliant Robin, (in spite of the fact most people erroneously refer to them as "Robin Reliant") but in fact produced a variety of different vehicles during a production run of over 60 years, including popular sports cars, convertibles and commercial vehicles. Around 1 to 2 million Reliant vehicles were produced, and were sold in at least 9 countries. For a period from the 1970s to the 1990s, Reliant was the UK's biggest British-owned car manufacturer.

Reliant Motor Company LTD is now a dormant company and the only part that still exists is Reliant partsworld which produce spares for Reliant vehicles and the Tempest sports car manufactured in Malvern.
