9922 Catcheller is a main belt asteroid. It orbits the Sun once every 3.72 years. It is associated with the Nysa family of asteroids.

Discovered on March 2, 1981 by Schelte Bus at the Siding Spring Observatory, it was given the provisional designation "1981 EO₂₁". It was later renamed "Catcheller", a portmanteau of Joseph Heller and Catch-22, the novel he authored, on the suggestion of Brian Marsden.
