Worldcon 75

The 75th World Science Fiction Convention, 9-13 August 2017, Messukeskus, Helsinki, Finland

Worldcon 77 Site Selection

Site Selection Process

The site of the World Science Fiction Convention (“Worldcon”) is determined two years in advance by a vote of the current Worldcon’s membership. To vote in Site Selection you must be Full Attending, “First Worldcon”, Youth, or Supporting Member of Worldcon 75 and pay the Advance Supporting Membership fee of $40 U.S. or €40. Payment in US dollars is only possible with a personal check or money order sent to the address in the USA. This process also makes you a Supporting Member of the winning bid’s convention.

Ballots and links for those wishing to pay the Advance Supporting Membership fee by credit card (in euros) are below. The paper ballot can be mailed to one of two addresses listed on the ballot. Only if you mail your ballot to the address in the USA may you pay for your voting fee with a personal check or money order in U.S. funds, payable to “77th Worldcon”. NO CHECKS are accepted to the address in Finland.

Although the WSFS Constitution allows electronic Site Selection balloting, Worldcon 75 has for several reasons decided opt out of this. The Site Selection Administrator and staff will, per the Constitution, be accepting only paper ballots either completed on site, mailed, or hand delivered, and will not accept ballots via any electronic means.

To pay your Advance Supporting Membership fee online, sign in to our member services site at and select “Payments” from the main menu available from the top left. If you are signed in, this direct link will also take you there.

Wednesday 9 August: 13:00 to 18:00
Thursday 10 August: 10:00 to 18:00
