We completely classify the bijections of the Thurston geometries that preserve geodesics as sets. For Riemannian manifolds that satisfy a certain technical condition, we prove that a totally geodesic subset is a submanifold. We also classify the geodesic-preserving bijections of the Euclidean cylinder \mathbbS1 × ℝ and the bijections of the hyperbolic plane ℍ2 that preserve constant curvature curves.
