Iced tea (or ice tea) is a form of cold tea. Though usually served in a glass with ice, it can refer to any tea that has been chilled or cooled. It may be sweetened with sugar, syrup and/or apple slices.

While most iced teas get their flavor from tea leaves (Camellia sinensis), herbal teas are sometimes served cold and referred to as iced tea. Iced tea is sometimes made by a particularly long steeping of tea leaves at a lower temperature (one hour in the sun versus five minutes at 80 to 100 °C (176 to 212 °F), which is known as sun tea.
