In this paper, we propose a generalization of Rényi divergence, and then we investigate its induced geometry. This generalization is given in terms of a ϕ-function, the same function that is used in the definition of non-parametric ϕ-families. The properties of ϕ-functions proved to be crucial in the generalization of Rényi divergence. Assuming appropriate conditions, we verify that the generalized Rényi divergence reduces, in a limiting case, to the ϕ-divergence.
