9933 Alekseev is a main belt asteroid. It orbits the Sun once every 3.16 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9933|title = 9933 Alekseev (1985 SM3)|work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-19]

Discovered on September 19, 1985 by Nikolai Chernykh and Lyudmila Chernykh working at the Crimean Astrophysical Observatory, it was given the provisional designation "mp|1985 SM|3". It was later renamed "Alekseev" after Anatolij Semenovich Alekseev, a professor at Novosibirsk University. [MPC 42359 "Minor Planet Center"]
