The 2013 Yorkshire Bank 40 tournament was the fourth and final season of the ECB 40 limited overs cricket competition for the English and Welsh first-class counties, plus Scotland, the Netherlands, and the Unicorns, a team of players who did not have first-class contracts.[1]
The competition consisted of three groups of seven teams, from which the top team from each group, plus the best second-placed team, progressed to the semi-finals.[1] The groups were allocated randomly.
In 2014, the ECB 40 was replaced with the 50-over Royal London One-Day Cup.
