DP Leonis (abbreviated DP Leo) is an eclipsing binary system approximately 1304 light-years away from the Sun,〔 probably a cataclysmic variable star of the ''AM Herculis''-type also known as ''polars''. The system comprises an eclipsing white dwarf and red dwarf in tight orbit (nearly 1.5 hours) and an extrasolar planet.〔
