A typical 1 cup pitted serving of sweet cherries contains 1.6 grams of protein (1.06 g per 100 g), which makes it only a minor source of protein. That covers roughly 3% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 7% of the calories in sweet cherries come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
