The 1923 County Championship marked the 34th edition of the first-class cricket competition in England. Seventeen teams competed across the season, with the final standings determined by a league system. Unlike a simple points total, the ranking relied on calculating the percentage of points gained against the total points available to each side.
Yorkshire claimed the title, securing their 12th championship in the process. Their campaign set the pace for the rest of the field throughout the summer. The team consistently navigated the challenges of the format to finish at the top of the table.
Scoring rules for the tournament provided clear incentives for positive play. Teams earned five points for a win. Matches that ended in a draw still offered a reward, as two points were granted to the side that won the first innings.
