Let n∈ \Bbb N-\1\, and let A be a Banach algebra. An additive map D: A→ A is called n-Jordan derivation if D(an)=D(a)an-1+aD(a)an-2+...+an-2D(a)a+an-1D(a), for all a ∈ A. Using fixed point methods, we investigate the stability of n--Jordan derivations (n--Jordan ^*-derivations) on Banach algebras (C^*-algebras). Also we show that to each approximate ^*-Jordan derivation f in a C^*- algebra there corresponds a unique ^*-derivation near to f.
