The 2017–18 Big Bash League season or BBL|07 was the seventh season of the Big Bash League, the professional men's Twenty20 domestic cricket competition in Australia.
The competition was extended to a total of 40 group games for the first time, each team playing ten matches in the group-stage.
Thirteen venues were selected to host the matches with Traeger Park, GMHBA Stadium and University of Tasmania Stadium all holding their first BBL match.
