Mary Jane Berlin pairs a cannabis trade-show floor with a full music festival across four days at Messe Berlin. The 2027 edition runs June 3 to 6, opening with a B2B conference day on the Thursday before festival programming starts on Friday. The door is strictly 18-plus, with no exception for accompanied minors.
What You're Walking Into
The format is really two events sharing a footprint. The exhibition floor is the daytime draw — brands, growers, seed houses and hardware companies working the halls at Messe Berlin's North Entrance. The festival is the other half, with stages running past the fair's own closing time on Friday and Saturday.
The organizers split the week deliberately. Thursday, June 3 is the B2B conference day, aimed at people working in the industry, and it carries no festival programming at all. Friday through Sunday opens up to everyone.
Hours, Day By Day
The organizer publishes each day separately, and they are not the same. Thursday, June 3 runs 11:00 to 18:00 with no festival. Friday, June 4 and Saturday, June 5 both run 11:00 to 20:00, with the festival going until 22:00. Sunday, June 6 runs 11:00 to 18:00, and the festival closes at 18:00 with it.
Getting There
Messe Berlin sits at Hammarskjoldplatz, 14055 Berlin, and the fair uses the North Entrance. The U2 stops at Theodor-Heuss-Platz and Kaiserdamm, and the S-Bahn ring — S1, S41, S42, S45 and S46 — stops at Messe Nord/ICC. Parking is free at car parks P1 and P2 in front of the North Entrance, though the organizer's own advice is to take the train, because the spaces go early.
The venue is ground level and barrier-free. If your disability pass carries a B, Bl, GL, aG or H mark, your companion is admitted free and you only buy your own ticket.
Age And Entry
The door is 18-plus and the organizer is blunt about how that works: being accompanied by a parent or another adult does not get a minor in. Build in time for security checks, which the organizer flags as slow on the busier days. A ticket on your phone is enough — nothing needs printing.
Tickets
Tickets for the 2027 edition are not on sale yet. The organizer is running a public countdown to October 31, 2026 and says to expect sales to open around then. The B2B day is available at a reduced rate to anyone already holding a Mary Jane Berlin event ticket. No 2027 prices have been published, so treat any figure circulating now as belonging to an earlier edition.
Our Read
The festival half is what separates this from a straight trade show, and it changes how you plan the trip — the day does not end when the halls close, and the Friday and Saturday nights are part of what you are paying for. If you are building a European run around cannabis, this and ICBC in April make Berlin the obvious anchor city for 2027.
