Servius Sulpicius Similis (died c. 125) was an eques of ancient Rome who held several imperial positions, both civil and military, under Trajan and Hadrian, culminating with praefectus or governor of Egypt from 107 to 112. His place of origin is unknown. A fragmentary inscription bearing Similis' name has been found in a cathedral in Carthage. This led Ronald Syme to comment, "An African 'patria' is not excluded".
