  Given a genus-$g$ Heegaard splitting of a 3-manifold, the Goeritz group is
defined to be the group of isotopy classes of orientation-preserving
homeomorphisms of the manifold that preserve the splitting. In this work, we
show that the Goeritz groups of genus-2 Heegaard splittings for lens spaces
$L(p, 1)$ are finitely presented, and give explicit presentations of them.
