(472271) 2014 UM33, provisionally designated 2010 TQ182, is a trans-Neptunian object and possible dwarf planet residing in the outer Kuiper belt. It was discovered on October 22, 2014, by the Mount Lemmon Survey. Its orbit was initially poorly determined, with 17 observations over 62 days, giving it an orbital uncertainty of 8. It is listed on Mike Brown's website as a probable dwarf planet, ranked 67th most likely.

It is approximately the size of 2 Pallas in the asteroid belt. On August 18, 2015, 2014 UM33 was found to have been discovered over four years previously, with the designation 2010 TQ182. This extended its observation arc to over 4 years, and then precovery observations were found using the Sloan Digital Sky Survey from 2009.
