The Montmorency cherry is a variety of sour cherry (Prunus cerasus). Montmorency cherries are part of the lighter-red Amarelle cultivar of sour cherries, rather than the darker-red Morello cultivar.

The tree produces large, light-red fruit (although some trees produce a darker red fruit). It is the very popular sour cherry and is extensively used in cherry pies, as well as in jams and preserves.

Montmorency cherries are also marketed in dried form, and Montmorency cherry juice and juice concentrate is also sold.

Since the early 21st century, the Montmorency cherry has been promoted as a healthful food, due to several purported health benefits.
