This study presents the first extensive distributional checklist of all the species of Lucanidae (Coleoptera) recorded from Turkey. A total of 13 species and 4 subspecies belonging to 4 genera of Lucanidae are listed from Turkey. New locality records, distributional records and ecological data are given. Because of reduced populations, some of these species under the threat of extinction in Turkey are in the IUCN Red List. It is important to protect them. Therefore, one aim of this study is to draw attention to these threatened species in Turkey and to add new information about them since not many studies have been conducted on these species.
