Whether it is old school and held in house (inappropriate use of the photocopier anyone?!), a casual drink in the local pub, or a proper sit down meal and entertainment at a local venue it is a chance to let your hair down and have a Christmas drink.
But a new survey has found that 19 per cent of UK adults have lied to try to avoid their works do and one in six dread the festive tradition.
Based on office party confessions and grumbles, TeamSport, which commissioned the survey have identified the top party personalities which appear every year.
So, which one are you?
The bad dancer – The one who thinks they can dance like Beyoncé after one too many, but actually ends up looking like David Brent.
The lightweight – The person who indulges in one too many Christmas tipples and ends up asleep in the corner an hour into the party.
The drunk boss – The one who usually lets their hair down the most, much to the amusement of the rest of the company.
The office flirt -The usually quiet colleague who truly comes out of their shell and outrageously flirts with anyone around them.
The checker inner – The person who is always connected to Facebook and checks everyone in at the party.
The driver – The one who spends the whole night drinking orange juice and regrets driving as they worry about who they will be driving home at the end of the night.
