The invention belongs to the field of aerodynamics, and discloses a rhombic missile-carrying wing lift line nonlinearity optimization design method and a rhombic missile-carrying wing. The optimization design method comprises the steps of selecting design variables; selecting a target function; determining a design point through a test design method; obtaining a target function corresponding to the design point through a numerical simulation method; establishing a response function of the target function and the design variable; and optimizing the objective function through a genetic algorithm to obtain final shape geometric parameters. The optimization design method solves the problem of large nonlinear change of the lift line slope caused by large aerodynamic interference of the front and rear airfoils of the rhombic back missile wing, and reduces the nonlinearity of the change of the lift line slope of the rhombic back missile wing along with the Mach number in the transonic speed range. According to the r
