Lucozade is a British brand of soft drinks and energy drinks manufactured and marketed by the Japanese company Suntory. Created as "Glucozade" in the UK in 1927 by a Newcastle pharmacist, William Walker Hunter, it was acquired by the British pharmaceutical company Beecham's in 1938 and sold as Lucozade, an energy drink for the sick. Its advertising slogan was "Lucozade aids recovery". It was sold mostly in pharmacies up until the 1980s before it was more readily available as a sports drink in shops across the UK.

An energy drink is a type of drink containing stimulant compounds, usually caffeine, which is marketed as providing mental and physical stimulation. They may or may not be carbonated and may also contain sugar, other sweeteners, or herbal extracts, among numerous other possible ingredients.
