Provided are a flying object control device, a flying object, and a program that can suppress occurrence of unintended turning in the flying object. A flying object control device has: a command value generation unit that generates a turning torque command value on the basis of a turning torque target value which is a target value of turning torque of a flying object; and an external disturbance countermeasure value generation unit that generates an external disturbance countermeasure value in accordance with turning torque generated by external disturbance, on the basis of the turning torque command value generated by the command value generation unit and a sensor detection value acquired by using a sensor provided to the flying object, wherein the command value generation unit generates the turning torque command value by subtracting the external disturbance countermeasure value generated by the external disturbance countermeasure value generation unit from the turning torque target value.
