The invention relates to a control method for preventing an aftereffect thrust from interfering with a rocket flying body, which comprises the following steps: S1, after a first-stage engine of a rocket is separated, starting an anti-interference control strategy at a second stage of the rocket to carry out anti-interference control flight; s2, after the anti-interference control flight in the step S1 is completed, the second stage of the rocket enters a subsequent flight stage; s3, after the second-stage engine of the rocket is separated, the third-stage engine of the rocket starts an anti-interference control strategy for anti-interference control flight; s4, after the anti-interference control flight in the step S3 is completed, the third stage of the rocket enters a subsequent flight stage; the specific process of anti-interference control flight comprises the steps that firstly, it is ensured that the rocket flight body is in a stable attitude state, then maneuvering control is conducted on the mass cent
