Every 100 kcal of pineapple brings 1.1 g of protein. On that measure it ranks 46th of the 71 fruits in this database and 763rd of all 796 foods on the site. Measured by weight instead, its 0.54 g per 100 g ranks 55th in its group.
Only about 4% of the calories in pineapple 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.
USDA lists 0.12 g of fat per 100 g of pineapple, too little for a protein-to-fat ratio to mean much.
Set against applesauce, another fruit entry in the database, a serving carries about 0.5 g more protein (applesauce has 0.4 g per 1 cup).
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 quoted here is measured by volume at 165 g, and it covers about 2% of the 50 g FDA Daily Value for protein.

0.54 g. The 1 cup chunks serving used on this page weighs 165 g and so carries 0.9 g.
How much protein do you get per 100 calories of pineapple?
1.1 g. That figure divides its 0.54 g of protein per 100 g by its 50 kcal per 100 g, so it does not depend on serving size.
Is the protein in pineapple complete?
No. On its own, the protein in pineapple is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of pineapple?
About 2%. One 1 cup chunks serving has 0.9 g, and the FDA Daily Value for protein is 50 g.
