Gunpowder tea is a form of green Chinese tea produced in Zhejiang Province of China in which each leaf has been rolled into a small round pellet. It is believed to take its English name from the fact that the tea resembles gunpowder pellets used for cannons. This rolling method of shaping tea is most often applied either to dried green tea (the most commonly encountered variety outside China) or Oolong tea.

Gunpowder tea production dates back to the Tang Dynasty (618–907) but it was first introduced to Taiwan in the 1800s. Although the individual leaves were formerly rolled by hand, today most gunpowder tea is rolled by machines (though the highest grades are still rolled by hand). Rolling tea leaves into gunpowder tea renders the leaves less susceptible to physical damage and allows them to retain more of their flavor and aroma. In addition, it allows certain types of oolong teas to be aged for decades if they are cared for by being occasionally roasted.

When buying gunpowder tea it is important to look for shiny pellets, which indicate that the tea is relatively fresh.
