Powdered tea is tea made or prepared from processed tea leaves that have been reduced to powder. It includes teas manufactured and sold as powders, such as matcha and powdered green tea made from sencha or other green teas, as well as historical preparations in which compressed tea was ground shortly before drinking.

Tea powder is processed tea leaf material from the Camellia sinensis plant that has been crushed, ground, or reduced into fine particles, granules, or dust-grade consistency.
