We analyze the stability of the Einstein static universe by considering linear homogeneous perturbations in the context of f(G) modified Gauss-Bonnet theories of gravity. By considering a generic form of f(G), the stability region of the Einstein static universe is parametrized by the linear equation of state parameter w=p/{rho} and the second derivative f{sup ''}(G) of the Gauss-Bonnet term.
