(35671) 1998 SN165 is a trans-Neptunian object. It was discovered on September 23, 1998 by A. Gleason at Steward Observatory.

It was originally classified as a plutino with a 2:3 mean-motion resonance with Neptune,[6] but further observations have established that it is a cubewano—a member of the classical Kuiper belt.[1]

With an estimated size of 393+39
38
 km
,[4] 1998 SN165 is a possible dwarf planet.
