The notion of Q7-brines and Q-instantons is introduced. These are one-half BPS solutions of the type IIB supergravity theory characterized by a set of three parameters p, q, r such that r(2) > 4pq. The numbers p, q, r parameterize the electric and magnetic couplings of, respectively, the Q7-branes and Q-instantons to a triplet of 8-forms. The (p, q) 7-branes and instantons including the D7-brane and the D-instanton have r(2) = 4pq. Seven-brane solutions containing Q7-branes are discussed and the Q-instanton on-shell action is computed. The Q7-branes are either novel bound states of a (p, q) 7-brane and a (p', q') 7-brane with (p, q) not equal (p', q') or they form an independent new object in the theory.
