Relevant data on the composition of mineral waters from 23 deposits and occurrences in the Crimean Peninsula are presented. The characteristic of 7 occurrences that have been previously unknown is presented. The studied waters are distinguished by broad-range variations in chemical composition, geochemical parameters of the medium, and the concentrations of biologically active components. Waters with the composition SO4-Cl-HCO3 Na, Cl Na, SO4-HCO3 Mg-Ca-Na, SO4-Cl Mg-Nam with TDS from ultra-fresh to brine level (0.4 - 202.9 g/dm3) are dominating. The waters relate to two large groups according to the geochemical parameters of the medium. The first group is characterized by reductive conditions with Eh from -330.2 to -22.3, pH from 7.3 to 9.1 and O2dissolved concentration 0.79 - 6.48 mg/dm3. The second group is characterized by oxidative Eh (+22.1 - +158.5), neutral and weakly alkaline pH (7,0 - 8,4), and O2dissolved concentrations from 2.73 to 6.92 mg/dm3. The studied waters exhibit a broad range of balneological properties, which allowed us to distinguish 13 types of mineral waters.
