In politics a common front is an alliance between different groups, forces or interests in pursuit of a common goal or in opposition to a common enemy. Other words that may be used are "alliance" or "coalition", though the term "common front" is often used when groups want to emphasise that their alliance is of a temporary nature and that individual groups within the front maintain their independence and do not consider themselves subservient to a collective leadership.

The practice of uniting with anyone one can against a common enemy is called frontism.

Historically, it has been a practice of Marxist-Leninist parties to unite with non-communist forces in revolution.

In left-wing politics there are two main types of common fronts: the popular front and the united front.
