Summary:In this article, we study \(p\)-adic torus periods for certain \(p\)-adic valued functions on Shimura curves coming from classical origin. We prove a \(p\)-adic Waldspurger formula for these periods, generalizing the recent work of Bertolini, Darmon, and Prasanna. In pursuing such a formula, we construct a new anti-cyclotomic \(p\)-adic \(L\)-function of Rankin-Selberg type. At a character of positive weight, the \(p\)-adic \(L\)-function interpolates the central critical value of the complex Rankin-Selberg \(L\)-function. Its value at a Dirichlet character, which is outside the range of interpolation, essentially computes the corresponding \(p\)-adic torus period.
