\begin{document}$R^2$\end{document} corrections to the dissociation of heavy quarkonium in the Gauss-Bonnet gravitational background. We analyze the impact of the Gauss-Bonnet parameter \begin{document}$\lambda_{\rm GB}$\end{document} on the spectral function of charmonium and bottomonium and examine the effect of \begin{document}$\lambda_{\rm GB}$\end{document} on the dissociation of heavy quarkonium. Our results show that \begin{document}$\lambda_{\rm GB}$\end{document} reduces the peak height and increases the peak width of the spectral function, suggesting that \begin{document}$\lambda_{\rm GB}$\end{document}enhances the dissociation of heavy quarkonium. We also discuss the variation in the dissociation of heavy quarkonium with the ratio of shear viscosity to entropy density and observe that the dissociation is easier in more perfect plasma. Additionally, we observe that the temperature decreases the peak height and widens the peak, thereby accelerating the dissociation."> <i>R</i><sup>2</sup> corrections to holographic heavy quarkonium dissociation -
