A maraschino cherry is a preserved, sweetened cherry, typically made from light-colored sweet cherries such as the Royal Ann, Rainier, or Gold varieties. In their modern form, the cherries are first preserved in a brine solution usually containing sulfur dioxide and calcium chloride to bleach the fruit, then soaked in a suspension of food coloring, sugar syrup, and other components.

A cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe.
