contents In this paper, we study the $p$-Laplacian system with Choquard-type nonlinearity $$ \begin{cases}-Δ_{p} u+(λa+1)|u|^{p-2} u=\frac{1}γ \left(R_α\ast F(u,v)\right)F_{u}(u, v), \\ -Δ_{p} v+(λb+1)|v|^{p-2} v=\frac{1}γ \left(R_α\ast F(u,v)\right)F_{v}(u, v),\end{cases} $$ on lattice graphs $\mathbb{Z}^N$, where $α\in(0,N),\,p\geq 2,\,γ> \frac{(N+α)p}{2N},\,λ>0$ is a parameter and $R_α$ is the Green's function of the discrete fractional Laplacian that behaves as the Riesz potential. Under some assumptions on the functions $a,\,b$ and $F$, we prove the existence and asymptotic behavior of ground state solutions by the method of Nehari manifold.
