We classify all warped product de-Sitter backgrounds in heterotic supergravity, up to two loops. We find that warped dSn backgrounds, with n≥ 3, are ℝ1,n× M9-n, where M9-n is a (9-n)-dimensional Riemannian manifold. Moreover, we establish that warped dS2 backgrounds are AdS3× M7, where M7 is a 7-dimensional Riemannian manifold.
