Cricket seasons are the times of the year when cricket is played.

Because top-class cricket is almost always played outdoors, on uncovered pitches, and rain prevents play, the seasons in each country are geared to coincide with the driest months of the year. The hours of daylight and the temperature are also factors in some countries. For example, in England the winter days are too short and often too dark, and the temperature is too low, for playing cricket to be practical. Normally, cricket is played outdoors but in the UK, cricket is played indoors when the season is finished.

When designating cricket seasons, the convention is to use a single year for a northern hemisphere summer season, and a dashed pair of years to indicate a southern hemisphere summer. Hence, 1948 for the English summer season and 1948–49 for the Australian summer that followed some months later. In the tropics, cricket can be played all year round. In the United Kingdom, the cricket season starts mid-April and ends in September, whereas in Australia, the cricket season begins in October and ends in February or March.
