This is a first for the brand, which has not done a festive brew before.
The limited edition will be exclusively available on draught in 29 Northampton pubs, with proceeds from sales donated to local charity, the Northamptonshire Community Foundation.
Master brewer Jon Elks has brewed the festive lager in the company's Northampton brewery.
It is described as having a, "full bodied taste with a balance of sweetness and bitterness" and is flavoured with Christmas spices, orange peel and cinnamon.
"This is the first time Carlsberg UK has brewed a Carlsberg beer for Christmas. We were inspired by our colleagues in Denmark, where the famous Tuborg Christmas beer, Julebryg, is so popular this time of year," said Liam Newton, vice president marketing at Carlsberg UK.
"We think beer-drinkers in Northamptonshire deserve a unique brew of their own and our brewers were proud to craft it for them."
The Christmas beer also has its own limited edition stemmed glass.
