Gliese 251, also known as HIP 33226 or HD 265866, is a star located about 18 light years away from the Solar System. Located in the constellation of Gemini, it is the nearest star in this constellation. It is located near the boundary with Auriga, 49 arcminutes away from the bright star Theta Geminorum, although due to its apparent magnitude of +9.89 it cannot be observed with the naked eye. The closest star to Gliese 251 is QY Aurigae, which is located 3.5 light years away.

Gliese 251 is a red dwarf with a spectral type of M3V with an effective temperature of about 3300 K. Its mass has been measured to be around 0.35 solar masses and its radius is about 45% solar radii. Its metallicity is less than that of the Sun, and is only 70% compared to that of the Sun. Observations at infrared wavelengths rule out the presence of a circumstellar disk around it.
