14827 Hypnos (also known by its provisional designation 1986 JK) is an Apollo near-Earth asteroid (NEA) discovered by Carolyn S. Shoemaker and Eugene Merle Shoemaker at Palomar Observatory on May 5, 1986. It is named after Hypnos, the Greek god of sleep.

Hypnos may be the nucleus of an extinct comet that is covered by a crust several centimeters thick that prevents any remaining volatiles from outgassing. Hypnos is frequently perturbed by Jupiter.

In 1958, Hypnos passed less than 0.03 AU from both Earth and Mars. Neither planet has been approached so closely by Hypnos since the 862 AD pass of Earth, or will be until the 2214 pass of Earth.

It has a well determined orbit and has been observed 170 times since 1986.
