Gliese 208 (Gj 208) is a red dwarf star with an apparent magnitude of 8.9. It is in the constellation of Orion 37 light years away.

The spectral type of Gj 208 has variously been described between K6 and M1. Two of the most recent observations give a statistically calculated spectral type of K7.9 or a more traditional classification of M0.0 Ve. It is a cool dwarf star and probably a spectroscopic binary.

Calculations from 2010 suggest that this star passed as close as 1.537 parsecs (5.0 light-years) from the Sun about 500,000 years ago.

Gj 208 is an RS Canum Venaticorum variable, close binary systems which show small amplitude brightness changes caused by chromospheric activity. Its visual magnitude varies by about a quarter magnitude with a period of 12.285 days.
