This paper is the first approach for analyzing the influence of {kappa}-distributed particles on the modified two-stream instability (MTSI). It is assumed that the plasma consists of a magnetized Maxwellian electron contribution and unmagnetized {kappa}-distributed ions drifting across the electrons. Within an electrostatic approximation, the influence of the {kappa} parameter on the maximum growth rate of the MTSI is evaluated for the special case of parallel drift velocity and wave propagation.
