Abstract: Most Asian territory of Russia is occupied by the basins of three largest Siberian rivers -- Ob, Yenisey and Lena discharging to the Arctic Ocean; the total drainage area of these river basins exceeds 7 mln sq. km. A great climate variability in combination with variable relief caused great variations not only in the dates of beginning and duration of different phases of ice events on the rivers of the study region but in the ice cover thickness, too. A general trend is an earlier appearance of ice events and later ice cover break-up in the direction from west to east. The duration of the complete ice coverage on the rivers of the Ob basin varies within 150–200 days on average; in the Yenisei river basin it varies from 160 to 220 days; in the Lena river basin -- from 180 to 230days. In southern parts of the study basins differences in their ice regimes are insignificant. Principal regular features of regimes of different ice events in the Siberian rivers, their space-time variability, conditions of formation and break-up are discussed in the paper
