2012–13 Ranji Trophy

The 2012–13 Ranji Trophy was the 79th season of the Ranji Trophy. It was contested by 27 teams divided into three groups of nine teams each. The top three teams from Groups A and B proceeded to the quarterfinals along with the top two teams from Group C. Mumbai won this year's trophy for the 40th time by beating Saurashtra in the final at the Wankhede.

The season had a different grouping system compared to that of the previous seasons, which had Elite and Plate divisions. The new system also increased the number of matches of the tournament. The points awarded to outright wins were increased from five to six in order to encourage results. The knock-out matches will be played across five days instead of four. All these changes were recommended by the BCCI's Technical Committee in June 2012.
