The Sheikh Zayed Grand Mosque (Arabic: جَامِع ٱلشَّيْخ زَايِد ٱلْكَبِيْر‎, romanized: Jāmiʿ Ash-Shaykh Zāyid Al-Kabīr) is located in Abu Dhabi, the capital city of the United Arab Emirates. The largest mosque in the country, it is the key place of worship for daily prayers, Friday gathering and Eid prayers. During Eid, it may be visited by more than 41,000 people

The Grand Mosque was constructed between 1996 and 2007. It was designed by Syrian architect Yousef Abdelky. The building complex measures approximately 290 by 420 m (950 by 1,380 ft), covering an area of more than 12 hectares (30 acres), excluding exterior landscaping and vehicle parking. The main axis of the building is rotated about 11° south of true west, aligning it in the direction of the Kaaba in Mecca, Saudi Arabia. Dimensions and alignment are estimated from satellite images; this information is not available at the Sheikh Zayed Mosque Web site as of 2014.

The project was launched by the late president of the United Arab Emirates (UAE), Sheikh Zayed bin Sultan Al Nahyan, who wanted to establish a structure that would unite the cultural diversity of the Islamic world with the historical and modern values of architecture and art. His final resting place is located on the grounds adjacent to the complex.

Sheikh Zayed Grand Mosque Center (SZGMC) offices are located in the west minarets. SZGMC manages the day-to-day operations and serves as a center of learning and discovery through its educational cultural activities and visitor programs.

The library, located in the northeast minaret, serves the community with classic books and publications addressing a range of Islamic subjects: sciences, civilization, calligraphy, the arts, and coins, including some rare publications dating back more than 200 years. The collection comprises material in a broad range of languages, including Arabic, English, French, Italian, Spanish, German, and Korean.
