Abstract
In this paper, using fixed point methods, we prove the fuzzy orthogonally $*$-$n$-derivation on orthogonally fuzzy $C^*$-algebra for the functional equation
\begin{align*}
\begin{split}
f(\frac{\mu x+\mu y}{2}+\mu w)+f(\frac{\mu x+\mu w}{2}+\mu y)+f(\frac{\mu y+\mu w}{2}+\mu x)
=2\mu f(x)-2\mu f(y)-2\mu f(w).
\end{split}
\end{align*}
