New preliminary electroweak results from the HERA lepton-proton collider experiments H1 and ZEUS are presented. These include new high Q2 neutral current cross section measurements and limits on a possible quark radius, in the search for contact interactions, and on the quark-Z couplings, extracted in combined electroweak and QCD fits. Furthermore, new charged current cross section measurements as a function of the lepton-beam polarisation are presented, as well as charged current measurement results, using the combined HERA I data from H1 and ZEUS. Finally, measurements of the single W boson production cross section and the W boson polarisation fractions are presented.
