Ḥarrat Rahāṭ () is a volcanic lava field in the Hejazi region of Saudi Arabia. In 1256 CE, a lava flow erupted from six aligned scoria cones, and traveled to within of the Islamic holy city of Medina; this was its last eruption. There were earlier eruptions, such as in 641 CE, which made finger-like flows to the east of the 1256 CE flow. It is the biggest lava field in Saudi Arabia. Nearby is Al Wahbah crater. There has been recent increase in seismic activitiy since 2009.
