[email protected] Received: 09.05.2020. Revised: 12.07.2020. Accepted: 11.08.2020. The article provides a relevant nomenclature list of Orchidaceae on the Black Sea coast in Krasnodarsky Krai (Russia), with clarification of the taxonomic status of each taxon. Fifty-one taxa (41 species and eleven subspecies) are known in the study area; apart of them, there are ten hybrids. Of them, five taxa are not found anywhere else in Russia, including Cephalanthera epipactoides, Epipactis euxina (endemic), E. leptochila subsp. neglecta, E. pontica, and Serapias orientalis subsp. feldwegiana. Two taxa (Epipactis condensata and Ophrys mammosa subsp. caucasica) slightly exceed the boundaries of the study area. Data on the distribution, occurrence, and association of species with plant communities are provided. Most taxa are more or less represented in forest communities. Only eight species are confined to grassland communities and ecotonic habitats. For 19 taxa, favourable conditions seem to be in anthropogenically disturbed habitats, preferring clearings under power lines, sides of forest roads, deposits, hay meadows, and dendroparks. Data on new locations and the state of the most threatened orchid species on the Black Sea coast in Krasnodarsky Krai are presented.
