A sharp minor is a minor scale based on A sharp. The A sharp minor scale consists of the pitches A sharp, B sharp, C sharp, D sharp, E sharp, F sharp, G double sharp and A sharp (harmonic minor scale). Its key signature consists of seven sharps.

Its relative major is C sharp major. Its parallel major is A sharp major, usually replaced by B flat major, since A sharp major has 10 sharps. The direct enharmonic equivalent of A sharp minor is B flat minor.

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary.

The enharmonic equivalent B flat minor is often used in most musical compositions instead of A sharp minor, thus indicating that A sharp minor is not a practical key for compositions and is one of the least used minor keys in music.
