The Nernst effect in superconductors is typically linked to fluctuating Cooper pairs above Tc or vortex motion below Tc. We show instead that Berry curvature of Bogoliubov quasiparticles can generate an intrinsic Nernst response in a clean, vortex-free superconducting state. Focusing on two-dimensional (2D) systems with Ising spin-orbit coupling, relevant to transition-metal dichalcogenides, we identify two regimes: an intervalley s-wave paired state where a weak magnetic field activates the effect, and an intravalley chiral p-wave paired state that exhibits a spontaneous charge or spin Nernst response without a field. We propose an experimental setup that circumvents screening and provide estimates of the signal magnitude. Our results establish the Nernst effect as a direct probe of Berry curvature and pairing symmetry in 2D spin-orbit-coupled superconductors.
