Brilliant Corners is a studio album by American jazz musician Thelonious Monk. It was his third album for Riverside Records, and the first, for this label, to include his own compositions. The complex title track required over a dozen takes in the studio.

Thelonious Sphere Monk was an American jazz pianist and composer. He had a unique improvisational style and made numerous contributions to the standard jazz repertoire, including "'Round Midnight", "Blue Monk", "Straight, No Chaser", "Ruby, My Dear", "In Walked Bud", and "Well, You Needn't". Monk is the second-most-recorded jazz composer after Duke Ellington.
