There is no doubt that culture represents a vital component of the foreign language curriculum. Over the past decades, foreign language textbooks, as a key element in the teaching and learning process, covered culture differently qualitatively and quantitatively, and the Arabic textbooks are no exception. This study aims to evaluate the presence of Arab culture in three main Arabic textbooks widely used in western institutions. The researcher applied a content analysis methodology to extract and examine the cultural aspects incorporated into these textbooks. The findings show a strong emphasis on the geographical, religious, and literary aspects and less focus on the societal and economic aspects and those related to the Arabs' daily lifestyle and leisure. The results could be used to decide which textbooks are more suitable for a specific curriculum and to help improve future educational material's content.
