(7888) 1993 UC is a near-Earth minor planet in the Apollo group. It was discovered by Robert H. McNaught at the Siding Spring Observatory in Coonabarabran, New South Wales, Australia, on 20 October 1993. The asteroid has an observation arc of years and has a well determined orbit. Its estimated size is 2.3 to 5.2 km.

On 20 March 2013, the asteroid passed 49 lunar distances or 0.12598 AU from Earth at a relative velocity of 21.8 km/s. The approach posed no threat to Earth. (7888) 1993 UC is not classified as a potentially hazardous asteroid (PHA) because its Earth MOID (Minimum Orbit Intersection Distance) is only 0.084 AU, and only objects with an Earth MOID less than 0.05 AU are considered PHAs.

It was discovered to be a binary asteroid by Arecibo Observatory in March 2013.
