G-sharp major is a major scale based on the musical note G-sharp, consisting of the pitches G♯, A♯, B♯, C♯, D♯, E♯ and F. Its key signature has six sharps and one double sharp.

For clarity and simplicitly, G-sharp major is usually notated as its enharmonic equivalent of A-flat major; however, it does appear as a secondary key area in several works in sharp keys - most notably in the Prelude and Fugue in C sharp major from Bach's Well-Tempered Klavier, Book 1. The G sharp minor prelude and fugue from the same set end with a Picardy third in G sharp major. G sharp major is tonicised briefly in several of Chopin's nocturnes in C sharp minor.

A section in the third movement of Chopin's first Piano Concerto is in G Sharp major, although the key signature has 4 sharps.

The final pages of the World Requiem by John Foulds are written in G sharp major with its correct key signature shown in the vocal score including the F.
