A survey of the Chrysididae (Insecta: Hymenoptera) of the Farasan Archipelago (Red Sea) was undertaken, mainly using Malaise traps and sweep nets from 2012 to 2017. Twenty-eight species belonging to eight genera were identified and recorded in this study (four of which are new records for the south-western Saudi Arabia). We have described four new species: (Hedychridium azizi sp. nov., Chrysis farasanensis sp. nov., Chrysis decolorata ssp. nov., Trichrysis flavicornis sp. nov.) A list of all species of Chrysididae recorded from the major Farasan Island is provided. The Chrysididae population of the Farasan Archipelago is composed mainly of species of South West Palaearctic Region. The presence of a few Afrotropical species is evidence of their expansion in the nearby Southern Arabia. Key word: Chrysididae, cuckoo wasp, Saudi Arabia, Jazan, Farasan Island, new species
