A typical 1 medium serving of baked potato contains 4.3 grams of protein (2.5 g per 100 g), which makes it a moderate source of protein. That covers roughly 9% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 11% of the calories in baked potato 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.
Among the 105 vegetables in the database, baked potato ranks 15th by protein per serving, and 523rd out of all 796 foods on the site. Set against beet greens, another vegetable entry in the database, a serving carries about 0.6 g more protein (beet greens has 3.7 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is counted by piece at 173 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
