Quasipaa spinosa is a species of frog in the family Dicroglossidae. It is known under many common names, including Chinese spiny frog, giant spiny frog, Chinese edible frog, and spiny paa frog. Its names refer to the distinctive characteristics of the species, relatively large size and the spiny chest of male frogs. Giant in frog terms only, it can nevertheless grow to lengths above 10 cm (4 in); this makes it the largest frog in Hong Kong.
