3184 Raab (1949 QC) is a main-belt asteroid and slow rotator, discovered on 22 August 1949 by E. L. Johnson at the Union Observatory, Johannesburg, South Africa.

In May 1996, following a proposal by Brian G. Marsden and Gareth V. Williams, the asteroid was named in honor of Herbert Raab, an Austrian software engineer, amateur astronomer and developer of the software Astrometrica.[3]

From observations made with the WISE space telescope, the diameter of the asteroid was determined to 19.3 kilometers, the albedo to 0.05.[2] The low albedo of this objects suggests that is a C-type asteroid.
