Z and W Physics with Tau-Leptons at the LHC

Measurements of the Z→ττ and W→τντ cross-sections in pp collisions at the LHC with data taken at are reported for the ATLAS, CMS, and LHCb experiments. Additionally, the polarization of τ-leptons produced from W→τντ events, as measured by ATLAS, is presented. All results are found to agree with the Standard Model.
