The 2013 FriendsLife T20 was the eleventh edition of what would later become the T20 Blast, a domestic Twenty20 English cricket competition. The competition ran from 26 June to 17 August 2013. The teams and format of the tournament remained the same as the previous season. Northamptonshire Steelbacks were champions, defeating Surrey in the final to win their first limited overs trophy since 1992.
The 18 teams were divided into three groups of six and each group played a double round-robin tournament. The top two teams from each group and the top two third-placed teams qualified for the knockout stage: a three-round single-elimination tournament. The top team from each group and the best second-placed team then played in a different quarter-final at their home ground. A free draw determined the placement of the remaining four teams and the semi-final and final match-ups.
