Rubus is a large genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae. Raspberries, blackberries, and dewberries are common, widely distributed members of the genus. Most of these plants have woody stems with prickles like roses; spines, bristles, and gland-tipped hairs are also common in the genus. The Rubus fruit, sometimes called a bramble fruit, is an aggregate of drupelets.

Most species are hermaphrodites, Rubus chamaemorus being an exception.

The blackberries, as well as various other Rubus species with mounding or rambling growth habits, are often called brambles. However, this name is not used for those like the raspberry that grow as upright canes, or for trailing or prostrate species, such as most dewberries, or various low-growing boreal, arctic, or alpine species.

The generic name means blackberry in Latin and was derived from the word ruber, meaning "red".

The scientific study of brambles is known as "batology".
