3406 Omsk is a main-belt asteroid discovered on February 21, 1969 by the Russian astronomer Bella Burnasheva at the Crimean Astrophysical Observatory, and given a preliminary designation of 1969 DA. It was named for the discoverer's birthplace of Omsk, the administrative center of the Omsk Oblast in Russia.
Photometric observations of this asteroid made in 2007 at the Mt. Tarana Observatory in Bathurst, Australia were used to produce a light curve that showed a period of 7.275 ± 0.006 hours with a brightness variation of 0.28 in magnitude. This indicates a ratio of 1.3 between the lengths of the major and minor axes.
