We investigate linearized gravity on a single de Sitter brane in the anti-de Sitter (AdS) bulk in the Einstein Gauss-Bonnet (EGB) theory. We find that Einstein gravity is recovered for a high energy brane, i. e., in the limit of a large expansion rate, i. e., for Hl≫1, where H is the de Sitter expansion rate and l is the curvature radius of the AdS bulk. We also show that, in the short distance limit, r≪min{l, H^<-1>}, Brans-Dicke gravity is obtained, whereas in the large distance limit, r≫max{l, H^<-1>}, a Brans-Dicke-type theory is obtained for Hl=O(1), and Einstein gravity is recovered both for Hl≫1 and Hl≪1. In the limit Hl→0, these results smoothly match the results known for the Minkowski brane.
