Keiko Ihara (井原 慶子, Ihara Keiko) (born July 4, 1973) is a Japanese auto racing driver and businesswoman. She was a former race queen, a model who appears in a swimsuit or other fashionable apparel at race circuits, before deciding to become a racing driver. She is one of the few Japanese women nationals to race internationally at a high level. Her best finishes in the British Formula Three Championship are two eighth places finishes in 2005, which helped her to a final championship standing position of 16th with 12 points. In the 2006 series, she finished in 17th and last position in the Championship Class, with four points.

Ihara joined the Gulf Racing Middle East to compete at the FIA World Endurance Championship in the LMP2 class with Jean-Denis Délétraz and Fabien Giroix as codrivers. In 2013, she raced two rounds for Gulf Racing Middle East and four with OAK Racing, both in the LMP2 class. The driver won the Fuji round of the 2014 Asian Le Mans Series for Oak Racing, together with Ho-Pin Tung and David Cheng.

As of 2025, Ihara is president of Future, a developer of hydrogen-assisted bicycles.
