Khaywan (Arabic: خيوان, romanized: Khaywān) is an old town and corresponding 'uzlah in Huth District of Amran Governorate, Yemen.

Early medieval texts indicate that Khaywan was an important stopping place on the pilgrimage route from Sanaa to Mecca at the time.

[2][3] In the year 286 AH (899-900 CE), Khaywan was the site of a major rebellion against Al-Hadi ila'l-Haqq Yahya, the Imam of Yemen.

The rebellion was led by one Ibn al-Dahhak (presumably to be identified with Abu Ja'far Ahmad ibn Muhammad), who led a nighttime attack on Khaywan after al-Hadi had left for Athafit, while his son Abu'l-Qasim had stayed behind.

The rebels were defeated, and al-Hadi had their houses and vineyards destroyed, but Ibn al-Dahhak himself managed to escape capture.
