Hooper was born in England but has not represented the national team at any level. In March 2011 it was thought that he may be eligible to represent Scotland. However, this possibility was later closed off. Since his move to Celtic he has been considered for England duty and was called up to the under-21 squad for a friendly but had to pull out due to injury. He was then included in the provisional squad for the 2011 UEFA European Under-21 Championship but did not go to the tournament.
