(119951) 2002 KX14 (provisional designation 2002 KX14) is a medium-sized trans-Neptunian object (TNO) residing within the Kuiper belt.

It was discovered on 17 May 2002 by Michael E. Brown and Chad Trujillo.

However, 2002 KX14 is not a plutino, as it is not actually in a resonance with Neptune, and it may have formed near its present nearly circular orbit lying almost perfectly on the ecliptic.

This TNO may have remained dynamically cold since its formation, and thus its orbit may not have been a direct result of significant perturbations from Neptune during its migration to the outer solar system.

The Deep Ecliptic Survey (DES) currently classifies it as a cubewano (classical) based on a 10-million-year integration of the orbit.
