Around 26% of the calories in pork belly come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 133 meats in the database, pork belly ranks 60th by protein per serving, and 83rd out of all 796 foods on the site. Set against ham steak, another meat entry in the database, a serving carries about 0.5 g less protein (ham steak has 23.1 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by weight at 85 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
The cut bacon is made from; fat makes up most of its weight even after cooking.
