A typical 2 tbsp serving of tahini contains 5.1 grams of protein (17 g per 100 g), which makes it a moderate source of protein. That covers roughly 10% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 11% of the calories in tahini 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 27 seeds in the database, tahini ranks 18th by protein per serving, and 487th out of all 796 foods on the site. Set against chia seeds, another seed entry in the database, a serving carries about 0.5 g more protein (chia seeds has 4.6 g per 1 oz).
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 measured by volume at 30 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
