In order to validate or invalidate a large class of low energy effectivetheories, the Swampland conjecture has attracted significant attention,recently. It can be stated as inequalities on the potential of a scalar fieldwhich is conjectured to satisfy certain constraints. In this work, we discussthe theoretical viability of deformed Starobinky gravity in light of therefined Swampland conjectures. We consider the deformation of the form$f(R)\sim R^{2(1-\alpha)}$ with $\alpha$ being a constant. We then constrain$\alpha$ using the spectral index of curvature perturbation $n_s$ and thetensor-to-scalar ratio $r$. We demonstrate that the model under considerationis in strong tension with the refined swampland conjecture. However, regardingour analysis with proper choices of parameters $a,\,b=1- a$ and $q$, wediscover that the model can always satisfy this new refined swamplandconjecture. Therefore, the model might be in landscape since the furtherrefining de Sitter swampland conjecture is satisfied.
