Small, round or elliptical, pore-like structures, resembling freckles, on the bark of some woody plants that allow gas exchange between the atmosphere and the interior tissues.

In most Vitis species of grapes, lenticels are absent on shoots but present on berries and pedicels. Density of lenticels on berries is low, and they are often filled with cuticular wax as the berries develop. Muscadine grapes (Muscadinia species) are distinguished from Vitis species of grapes by the presence of lenticels on shoots.
