Dalam teori probabilitas dan statistika, distribusi F merupakan distribusi probabilitas kontinu. Distribusi F juga dikenal dengan sebutan distribusi F Snedecor atau distribusi Fisher-Snedecor (setelah R.A. Fisher dan George W. Snedecor). Distribusi F sering kali digunakan dalam pengujian statistika, antara lain analisis varians dan analisis regresi.
