Orientalism is the study of Near and Far Eastern societies and cultures, languages, and peoples by Western scholars. It can also refer to the imitation or depiction of aspects of Eastern cultures in the West by writers, designers and artists.

In the former meaning, the term Orientalism has come to acquire negative connotations in some quarters and is interpreted to refer to the study of the East by Westerners shaped by the attitudes of the era of European imperialism in the 18th and 19th centuries. When used in this sense, it implies old-fashioned and prejudiced outsider interpretations of Eastern cultures and peoples. This viewpoint was most famously articulated and propagated by Edward Said in his controversial 1978 book Orientalism, which was critical of this scholarly tradition and also of a few modern scholars, including Princeton University professor Bernard Lewis.
