9930 Billburrows is a C-type main belt asteroid. It orbits the Sun once every 3.80 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9930|title = 9930 Billburrows (1984 CP)|work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-18]

Discovered on February 5, 1984 by Ted Bowell working at the Anderson Mesa Station of the Lowell Observatory, it was given the provisional designation "1984 CP". It was later renamed "Billburrows" after William E. Burrows, a professor at New York University who founded the Science, Health and Environmental Reporting school there. [cite web|url = http://journalism.nyu.edu/prospectivestudents/coursesofstudy/serp/faculty.html|title = Journalism at NYU - Science, Health and Environmental Reporting|publisher = New York University] The name was suggested by E. M. Standish. [MPC 43043 "Minor Planet Center"]
