Saada (Arabic: صَعْدَة, romanized: Ṣaʿdah) or Sa'dah is one of the governorates of Yemen. The governorate's seat and the largest city is Saada. It is the epicentre of Zaydism and where the Houthi group originates from.

Saada is 240 kilometers north of the capital Sanaa. Northwest of its capital, Saada city, the terrain of the governorate becomes increasingly mountainous and reaches elevations of 2,050 meters in the far west. Between these mountains and Saada city, the terrain is peppered with basins and wadis, ultimately dropping to form arid plains in the east. Rainfall varies greatly according to location. The western mountains of Razih receive as much as 1,000 mm per year, while arid regions east of the governorate's capital can get as little as 50 mm. Given the scarce amounts of arable land in these arid areas, most of the governorate's population lives in the wetter west.
