Orange juice refers to the juice of oranges. It is made by extraction from the fresh fruit, by desiccation and subsequent reconstitution of dried juice, or by concentration of the juice and the subsequent addition of water to the concentrate. In American English, the term OJ may also be used to refer to orange juice.

A typical serving of orange juice has 120 mg of vitamin C (>100% RDI). It has 21 g of sugars and has 110 calories, both close to a can of soda. It also supplies potassium, thiamin, and folate.

Citrus juices contain flavonoids (especially in the pulp), that may have health benefits. Orange juice is also a source of the antioxidant Hesperidin. Due to its citric acid content, orange juice is acidic, with a typical pH of around 3.5.

Common orange juice is made from the sweet orange. Different cultivars (e.g. Valencia, Hamlin) have different properties, and a producer may mix juices to get the desired taste.

The blood orange is a mutant of the sweet orange. Blood orange juice is popular in Italy, but may be hard to find elsewhere.
