(4177) Kohman is a main belt asteroid discovered by Edward LG Bowell on September 21, 1987 at the Anderson Mesa Station of the Lowell Observatory .

The asteroid's orbit around the Sun is in a 2: 1 resonance with the orbit of Jupiter . This resonance zone is called the Hecuba gap. There are only a few asteroids there. It is assumed that the orbit of (4177) Kohman is stable for only about 100 to 500 million years, so it is assigned to the Griqua asteroids, named after (1362) Griqua , the first and so far largest asteroid discovered with these properties.

(4177) Kohman was named after Truman Paul Kohman (* 1916), a co-discoverer of the aluminum isotope 26 Al.
