Scenic design (also known as scenography, stage design, set design or production design) is the creation of theatrical, as well as film or television scenery. Scenic designers have traditionally come from a variety of artistic backgrounds, but nowadays, generally speaking, they are trained professionals, often with M.F.A. degrees in theatre arts.

The "stage picture" is the "look" or physical appearance of the stage for a play, whether in rehearsal or performance. It reflects the way that the stage is composed artistically in regard to props, actors, shapes and colours. The stage picture should express good principles of design and use of space. It should be visually appealing for the audience or should express the show's concept.

The scenic designer is responsible for collaborating with the theatre director and other members of the production design team to create an environment for the production and then communicating the details of this environment to the technical director, production manager, charge scenic artist and propmaster. Scenic designers are responsible for creating scale models of the scenery, renderings, paint elevations and scale construction drawings as part of their communication with other production staff.
