The 2015 season marks Glamorgan County Cricket Club's 128th year of existence and its 94th as a first-class cricket county. In 2015, Glamorgan is playing in the Second Division of the County Championship, Group B of the 50-over Royal London One-Day Cup and the South Group of the NatWest t20 Blast. It is the second season in charge for head coach Toby Radford. The club captain is overseas player Jacques Rudolph. Unlike other counties, Glamorgan is competing in limited-overs cricket without a nickname for the third year in a row.
