This paper describes the state of the NE Black Sea coasts in the 21^st century. The modern development and economic use of these coasts in the conditions of climate change and anthropogenic load are analyzed. A geomorphological feature of the Black Sea coast of the Caucasus is the predominance of denudation processes over accumulative ones. There is only one large accumulative sandy section—the Anapa Bay-Bar. Abrasion shores with narrow beaches are widespread in the NE part of the Russian Black Sea coast. There is no united longshore sediment flux. Local lithodynamic cells on concave sections of the shore are characteristic. The conditions of these shores are favorable for the use of local coast protection. In the SE section, the dynamics of the shores in natural conditions were determined by the sediment balance. The active abrasive processes were combined with a large volume of beach-forming sediments carried out by rivers. Up to the middle of the 20^th century, there was a single longshore sediment flux toward the SE and broad beaches near river mouths. The Imereti Lowland was formed between the mouths of the Mzymta and the Psou rivers. Irrational and excessive technogenic transformation of the shoreline and river basins in 20^th century resulted in a progressive lack of sediment supply. Since the beginning of the 21^st century, the width of the beaches has been decreasing throughout the entire area, and the stability of the coast has been maintained artificially by shore protection structures. The Russian sector of the Caucasus Black Sea coast is now densely populated and is an important recreational and economic zone. The main problems that had to be solved in the past and will have to be solved in the future are the shortage of beaches and the protection of the coast and objects located on it from wave impacts.
