1804 Chebotarev, provisional designation 1967 GG, is a stony asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 6 April 1967, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.

The stony S-type asteroid orbits the Sun at a distance of 2.4–2.5 AU once every 3 years and 9 months (1,367 days). Its orbit has an eccentricity of 0.02 and an inclination of 4° with respect to the ecliptic. Chebotarev was first identified as 1938 QL at Yerkes Observatory in 1938, extending the body's observation arc by 29 years prior to its official discovery observation.

In February 2004, a rotational light-curve of Chebotarev was obtained from photometric observations by French amateur astronomer Laurent Bernasconi. It gave a well-defined rotation period of 4.026 hours with a brightness amplitude of 0.41 magnitude (U=3).

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Chebotarev measures 9.15 kilometers in diameter, and its surface has a high albedo of 0.501, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 10.79 kilometers based on an absolute magnitude of 12.2.

This minor planet was named in honor of Soviet astronomer G. A. Chebotarev (1913–1975), who was a professor and the director of the Institute of Theoretical Astronomy as well as president of IAU's Commission 20, (Positions & Motions of Minor Planets, Comets & Satellites). He is known for his work on celestial mechanics of asteroids, comets and satellites. Naming citation was published before November 1977 (M.P.C. 3569).
