The online ballot for free tickets to what is one of the main events in the city's festive calendar opens on Monday.
It will remain open until Sunday, September 29, with more than 12,000 tickets to be distributed to revellers.
Lord Provost of Glasgow Sadie Docherty said: "Summer shone brightly this year, which was fabulous and our Christmas lights switch-on will ensure Glasgow continues to shine as we countdown to Christmas and all the fun that entails.
"The event marks the start of the festive season, with Glasgow's biggest Christmas party in the shadow of the City Chambers.
"Places at this much-loved event are always in great demand and the ballot application process ensures a fair distribution of tickets.
"I would urge those without online access to go to any one of the city's 33 libraries, they are ready and willing to help you get your name in the hat."
Tickets will be allocated by public ballot, with names drawn randomly, and applicants will be advised if they have been successful by email on October 8.
People can apply for a maximum of six tickets, but can only apply ONCE, as only one application per address will be permitted into the ballot system.
The online ballot system, run by Glasgow Life, was introduced in 2012 and last year was five times oversubscribed.
