Abstract: (Elsevier B.V.)

In this paper, we construct a thin-shell wormhole (TSW) in

4 D

Einstein–Gauss–Bonnet gravity (EGB) and examine the stability condition of the wormhole (WH) by using the linear and nonlinear models of the exotic fluid at the throat

(a_{0})

. In addition, we have checked the validity of null, weak, and strong energy conditions for the TSWs. The energy conditions are observed to violate the linear model but it satisfies the nonlinear model. Further,

4 D

EGB wormhole solutions are found to exist for a particular choice of equilibrium radius as well as the equation of state parameter.
