We demonstrate the existence of two-field Q-ball solutions of the scalar
field equations of supersymmetric D- and F-term hybrid inflation. The solutions
consist of a complex inflaton field together with a real symmetry breaking
field. Such inflatonic Q-balls may play a fundamental role in reheating and the
post-inflation era of supersymmetric hybrid inflation models.
