Benedict's reagent (often sold as Benedict's Qualitative Solution or Benedict's Solution) is a chemical reagent named after an American chemist, Stanley Rossiter Benedict.

Benedict's reagent is a chemical reagent commonly used to detect presence of reducing sugars, however other reducing substances also give a positive reaction. This includes all monosaccharides and many disaccharides, including lactose and maltose. Such tests that use this reagent are called the Benedict's tests.
