Aravah (Hebrew: ערבה, pl. aravot - ערבות) is a leafy branch of the willow tree. It is one of the Four Species (arbaʿath haminim - ארבעת המינים) used in a special waving ceremony during the Jewish holiday of Sukkot. The other species are the lulav (palm frond), hadass (myrtle), and etrog (citron).
The aravah is also used for a separate ceremony on Hoshanah Rabbah, the last day of Sukkot, when five branches are beaten against the ground to the accompaniment of special verses.
