The 1902 County Championship served as the 13th edition of the competition. Fifteen teams participated in the tournament, which ran between 1 May and 6 September. All matches followed the traditional three-day first-class format.
Yorkshire secured the title once again, marking their sixth championship victory. This win also represented the third consecutive season that Yorkshire finished at the top of the league table. Sussex claimed second place, which stood as their highest finish in the competition to that point.
The league operated on a specific points system. Teams received one point for a win and lost one point for every defeat. The final standings were calculated by dividing the points earned by the total number of completed matches, then multiplying that figure by 100 to determine the final percentage.
Across the 156 matches played, individual performances shaped the season. Bobby Abel of Surrey led the run-scoring charts with 1,570 runs. Meanwhile, Fred Tate of Sussex dominated the bowling statistics by taking 153 wickets throughout the summer.
