Aldiwan Arabic Language Center, briefly Aldiwan Center, is an Arabic language school based in Cairo, Egypt and established in 1997. It focuses on providing Modern Standard Arabic (MSA) certificates and Egyptian Colloquial Arabic (ECA) courses.

Aldiwan Center has itself used, and has been referred to by others, by many similar names in spelling and in pronunciation on websites, advertising, and printed materials.

This might refer to the variety of writing choices in writing the same Arabic word Diwan (Arabic: ديوان precedented by Al (Arabic: ال, which is the definite article in Arabic; in English, to be: Aldiwan (Arabic: الديوان, as one word, not two separate words: the article, as there is no article in English named "Al" unless the user wants to show that it is an article, then the name itself. The term Diwan or Divan (دیوان) is a Persian word and can refer to:

• Divan or diwan, an oriental high governmental body, such as the Imperial council in the former Ottoman Empire and its successor states
• Diwan (title) (dewan or divan), a number of Middle Eastern titles used in various languages for high officials, especially of cabinet rank, or as a rank of nobility in South Asia

The center is nationally accredited as an Arabic language instruction school in Egypt.

Aldiwan Center is an Arabic language school, whose main focus is language instruction, while providing Tajwid, and Arabic calligraphy courses is extra effort on the behalf of Aldiwan to enhance the students' skills, but not the mainstream.

Aldiwan Center has published many textbooks for teachers of Arabic as a foreign language, compared to those of the American University in Cairo and other reputable academic institutions, which resulted in a positive opinion of some students. It also kept interest in incorporating technology in its learning materials, as voice overs of its textbooks and multimedia presentations. Outside the classroom materials they developed electronic dictionaries and how-to guides.

Aldiwan Center has been in a high-profile with many of the US students and professors of high-ranking universities who elect to use its services. Aldiwan has been publishing for years its acceptance of US and Canadian universities’ scholarships with positive testimonials from their students.

While Aldiwan Center refers its reputation to its core team of highly qualified teachers who have graduate diplomas in teaching Arabic as a foreign language and their methods of instruction, some old students assure Aldiwan of the practicality and one-on-one tutoring it facilitates.
