A bramble is any rough, tangled, prickly shrub, usually in the genus Rubus, which grows blackberries, raspberries, or dewberries. "Bramble" is also used to describe other prickly shrubs, such as roses (Rosa species). The fruits include blackberries, arctic brambleberries, or raspberries, depending on the species, and are used to make jellies, jams, and preserves.

In British English, bramble usually refers to the common blackberry, Rubus fruticosus. R. fruticosus grows abundantly in all parts of the British Isles, and harvesting the fruits in late summer and autumn is often considered a favourite pastime. An especially hardy plant, bramble bushes can also become a nuisance in gardens, sending down strong suckering roots amongst hedges and shrubs and being particularly resilient against pruning. Many consider R. fruticosus a weed due its tendency to grow in neglected areas and its sharp, tough thorns, which can be hazardous to children and pets.
