The auction will raise money for The Archie Foundation who support sick and bereaved children, and their families, across the north and north-east.
Eight 7.5 foot fir trees that have been specially pre-lit and decorated by local companies will be sold to the highest bidders. It will raise 'essential' funds for the charity which is based at The Royal Aberdeen Children's Hospital.
A virtual auction went live today (Monday 22 November) and will culminate in an in-person event at Marischal Square on Thursday.
Lynne Brooks, The Archie Foundation’s Gifts and Donations officer said: "Our Christmas tree auction is a firm festive highlight and yet again our incredible sponsors have pulled out all the stops to create eight uniquely decorated trees that will look fantastic in any living room.
"This time of year can be a stressful and daunting time for children who are facing Christmas in hospital and their families. The money raised from the auction, along with other fundraising activities, not only helps us to bring some festive cheer to the children’s wards but also funds critical services such as family accommodation to ease some of the worries during what can be a difficult time."
One of the highlights of the auction is expected to be a rainbow-themed tree using knitted rainbows that have been sent-in by members of the public.
The trees have been decorated by TAC Healthcare, CMS Law, Adesso and Koi Thai.
Phil Webb, CEO or TAC Healthcare said: "The Archie Foundation is one that is close to our hearts, and we're pleased to once again be supporting this important charity. The team raises the bar every year and this year have really surpassed themselves. The trees will make a great addition to any home this Christmas and I’m hopeful people will once again dig deep and help exceed last year’s impressive auction total."
Last year’s Christmas Tree auction raised £12,000 and organisers are hopeful that "the generous north-east community will once again show their support for this important cause."
The pre-lit trees and decorated trees are currently on display at Marischal Square before they go under the hammer. They will be delivered to their new owners the following week in time for them to be displayed at home throughout the festive period.
