Cosmic Voids, vast regions of relatively empty space within the large-scale structure of the Universe, are currently entering the realm of precision cosmology. Most ongoing and upcoming redshift surveys are considering them as a cosmological probe in one way or another. The aim is to extract information that is not accessible via the traditional probes. I will present some recent highlights from the analysis of cosmic voids in both simulated, as well as observational data. These include constraints on cosmological parameters from dynamic and geometric distortions of voids in SDSS with prospects for Euclid, measurements of gravitational lensing around voids in DES, and their expected signatures from primordial non-Gaussianity and massive neutrinos in simulations.
