Lemonade is a sweetened lemon-flavored drink.

There are varieties of lemonade found throughout the world. In North America and South Asia, lemonade is typically non-carbonated and non-clarified (called "cloudy lemonade" in British English). It is traditionally a homemade drink using lemon juice, water, and a sweetener such as cane sugar, simple syrup, maple syrup or honey. In the United Kingdom, Ireland, Central Europe, South Africa, Australia, and New Zealand, a carbonated lemonade soft drink is more common. Despite the differences between the drinks, each is known simply as "lemonade" in countries where it is dominant.

The suffix "-ade" may also be applied to other similar drinks made with different fruits, such as limeade, orangeade, or cherryade.
