We present a novel, exact, traversable wormhole (T-WH) solution for$(3+1)$-dimensional Einstein-scalar-Gauss-Bonnet theory (EsGB) coupled to apower-Maxwell nonlinear electrodynamics (NLED). The solution is characterizedby two parameters, $\mathcal{Q}\!_{\rm e}$ and $\mathcal{Q}\!_{_{ \mathcal{S}}}$, associated respectively with the electromagnetic field and the scalarfield. We show that for $\mathcal{Q}^2_{\rm e} - \mathcal{Q}\!_{_{ \mathcal{S}}}>0$ the solution can be interpreted as a traversable wormhole. In the generalcase, with non-vanishing electromagnetic field, the scalar-Gauss-Bonnet term(sGB) is the only responsible for the negative energy density necessary for thetraversability. In the limiting case of vanishing electromagnetic field, thescalar field becomes a phantom one keeping the WH throat open and in this casethe Ellis WH solution \cite{Ellis} is recovered.
