2015 English cricket season
The 2015 English cricket season was the 116th in which the County Championship had been an official competition. It began in April with a round of university matches, and continued until the conclusion of a round of County Championship matches in late September. Three major domestic competitions were contested: the 2015 County Championship, the 2015 Royal London One-Day Cup and the 2015 NatWest t20 Blast.
During this season, two international teams toured England. New Zealand toured early in the summer, with Australia also touring later in the year. The latter tour saw England win The Ashes Test series 3-2; it was the 78th test series between the two sides.
