F{{sharp}} (F-sharp; also known as fa dièse or fi) is the seventh semitone of the solfège.

It lies a chromatic semitone above F and a diatonic semitone below G, thus being enharmonic to sol bémol or G♭ (musical note) (G-flat) in 12 equal temperament. However, in other temperaments, such as quarter-comma meantone, it is not the same as G{{music|flat}}. G{{music|flat}} is a major third below B{{music|flat}}, whereas F{{music|sharp}} is a major third above D (a minor third below A). Another enharmonic note is E{{music|double sharp}} (E-double sharp).

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the F{{music|♯}} above middle C (or F{{music|#}}4) is approximately 369.994Hz.{{cite web|last=Suits|first=B.
