(120348) 2004 TY364, also written as (120348) 2004 TY364, is a trans-Neptunian object. It is an inner classical Kuiper belt object in the definition by Gladman, Marsden, and Van Laerhoven (e<0.24). Its inclination of almost 25 degrees disqualifies it as such in Marc Buie's definition. It is also not listed as a scattered disc object by the Minor Planet Center. It was discovered by Michael E. Brown, Chad Trujillo and David L. Rabinowitz on October 3, 2004 at the Palomar Observatory.
With an absolute magnitude of 4.5, it is likely a dwarf planet. However, light-curve analysis has questioned whether it really is one.
As of 2014, it is 39.2 AU from the Sun.
