(52760) 1998 ML₁₄ (also written (52760) 1998 ML14) is an as unnamed, near-Earth, Mars-crossing, potentially hazardous asteroid. It was discovered by LINEAR in 1998.^[1] It is approximately 1.5 km in diameter.

Shortly after its discovery, 1998 ML₁₄ was imaged by radar at Goldstone and Arecibo.^[2] The study showed that the asteroid has a rotation period of 15 hours, and a shape that is roughly spherical, with some steep protrusions and large craters.

On August 24, 2013 it passed at a distance of 21.9 Lunar distances.^[3] It was hoped to be observed by Goldstone radar.^[4]
