Rada'a (Arabic: رداع) is a walled city in south-east Yemen, although today the city is grown considerably beyond its walls. Located in the Al-Bayda' governorate, Rada'a is the largest and most important of its cities. It was once the home of the second largest Jewish community in Yemen, after Sana'a.
Rada'a is located some 31 miles (50 km) from Dhamar. The city's most prominent feature is Rada'a castle.
