Barquentine is a fictional character in Mervyn Peake's Gormenghast series. He is the son of Sourdust, the Master of Ritual of Gormenghast Castle. He is a one-legged, hunchbacked dwarf with a bitter, vicious personality; he never washes, he dresses in filthy rags, and his hair and beard are long, tangled, and dirty. He is frequently taunted by the castle's children, who sing "Rotten leg, rotten spine - ya! ya! Barquentine!"
