Amiriya Madrasa  Al-Amiriya () is a 16th-century madrasa (educational institution) located in Rada, Yemen. It is under consideration for inscription as a UNESCO World Heritage site. It was built in 1504 and is an example of the architecture of Tahirids, Yemen. The monument was in poor condition until 1978 when Iraqi-born archaeologist Selma Al-Radi saw it and enlisted financial help from foreign missions to restore it in a more than twenty-year effort which she led. This site was added to the UNESCO World Heritage Tentative List on July 8, 2002, in the Cultural category. The restoration process revived the art of qadad, a form of waterproof interior and exterior plastering. In 2004 a documentary film, "Qudad, Re-inventing a Tradition", was made on the subject by the filmmaker Caterina Borelli (preview). The restoration of the Amiriya Complex was awarded the Aga Khan Award for Architecture in 2007.
