A line producer is a key member of the production team for a motion picture. Typically, a line producer manages the budget of a motion picture. Alternatively, or in addition, they may manage the day to day physical aspects of the film production, serving a role similar to the unit production manager.

Line producers usually do not act as part of the creative team for a picture. Because line producers work on location, they don't work on more than one film at a time (unlike other producer roles).

A line producer may also hire key members of the crew, negotiate deals with vendors, and is considered the head of production on the set.
