  In this paper, we study the action of a Dynkin automorphism $\sigma$ of a
simple Lie algebra $\mathfrak{g}$ on the generalized Gaudin algebras. In
particular, we show isomorphisms between the coinvariants of the generalized
Gaudin algebras associated with $\mathfrak{g}^\vee$ and the generalized Gaudin
algebras associated with $\mathfrak{g}_\sigma^\vee$, where
$\mathfrak{g}_\sigma$ is the fixed point subalgebra.
