Scenography is the practice of making theatre including sets, costumes and texts from a theoretical and practical point of view. Scenographers work from the premise of a space that is constructed, updated, transformed and filled. The role of the scenographer is analogous to that of the dramaturg.

The word "scenography" is of Greek origin, coming from the words "skini" meaning "stage" and "grafo", meaning "to write or to describe". So the actual meaning of the word is "to describe something on stage". More recently, the word is also used for museography, the art of designing museum and exhibition sets.
