2014 OE394 is a large cubewano in the Kuiper belt that was discovered in July 2014 by the Pan-STARRS-1 telescope, and announced on 17 July 2016. It is one of the brighter trans-Neptunian objects, being the 34th brightest cubewano as of 23 July 2016. Its exact size is unknown, but is most likely between 240 and 730 kilometers across. Mike Brown's website lists it as a "possible" dwarf planet, with an estimated diameter of 337 kilometers.

2014 OE₃₉₄ is also somewhat close to the New Horizons probe, about 8.7 AU away on 1 January 2017, and 7.5 AU on 1 January 2019. Considering its large size, it would make a possible imaging target, as 15810 Arawn was in early 2016. However, as 2014 OE₃₉₄ is currently over 10 times further than the other was, it would have much lower-precision data.
