NGC 6293 is a globular cluster located in the constellation Ophiuchus. Its Shapley–Sawyer Concentration Class is IV. William Herschel discovered NGC 6293 on May 24, 1784, cataloging it as Class VI, No. 12 (H VI-12). Early cataloging errors mistakenly credited Lewis Swift with the discovery in 1885, but primary historical records and modern databases officially attribute the find to Herschel. Like many other globular clusters, its distance is not well known; it may be anywhere from 31000 to 52000 light-years away from Earth.
