Prune has several meanings:

• Any of more than 125 varieties of fruit, most grown for drying. Four of the most common varieties are French, Imperial, Italian, and Green Gage. Prunes are cultivars of plum species (mostly Prunus domestica). In general, prunes are freestone cultivars (the stone is easy to remove), whereas plums are cling (the stone is more difficult to remove). Dried fruit of the prune tree were traditionally called "dried prunes" or "prunes", but an effort is currently underway to market them as "dried plums". Fresh prunes reach the market earlier than fresh plums and are usually smaller in size. Prune juice is more fiber-rich than plum juice and is often marketed as a way to increase regularity.

In the United States, due to the negative association of prunes with regularity and the elderly, the California Dried Plum Board renamed and began remarketing prunes as "dried plums".

Also:

• A dried prune.
• A dried plum
• A slang term for an elderly person, from the resemblance of the wrinkled skin to that of a dried prune.
• The verb to prune, to cut back plants - see pruning.
• Pilot Officer Prune: A World War Two British cartoon character used in training aids.
