Father Christmas will take time out from his busy schedule to turn on the lights in Union Street at 4pm.
Aldershot's town centre management team is hoping a big crowd of shoppers will attend the ceremony.
To make the occasion extra special presents galore are being handed out in the town centre prize draw.
Aldershot retailers have donated more than 80 prizes.
The first four lucky winners will receive a cash prize from the News Group.
"The generosity of Aldershot's retailers is simply fantastic," said town centre manager Jennifer Rawlings.
"Never before have we had so many prizes given to us, and the Christmas draw is completely free to enter," she added.
To enter the draw, put your completed entry form into one of the boxes in The Galleries or the Wellington Centre.
Entry forms have been distributed with the Courier newspaper and are also available from many shops throughout the town.
The draw will take place straight after the town centre lights are switched on.
