We investigate the strong gravitational lensing of spherically symmetricblack holes in the novel Einstein-Gauss-Bonnet(EGB) gravity surrounded byunmagnetised plasma medium. The deflection angle in the strong deflection limitin EGB spacetime with homogeneous plasma is derived. We find that both thecoupling constant $\alpha$ in the novel EGB gravity and the presence of plasmacan affect the radius of photon sphere, strong field limit coefficient andother lensing observables significantly. While plasma has little effect on theangular image separation and the relative magnifications as $\alpha/M^2\to -8$and $\alpha/M^2\to 1$, respectively.
