We present, for the first time, recoil velocity estimates for binary neutronstar mergers using data from numerical relativity simulations. We find thatbinary neutron star merger remnants can have recoil velocity of the order of afew tens of km/s and as high as $150$ km/s in our dataset. These recoils areattained due to equivalent contributions from the anisotropic gravitationalwave emission as well as the asymmetric ejection of dynamical matter during themerger. We provide fits for net recoil velocity as well as its ejecta componentas a function of the amount of ejected matter, which may be useful whenconstraints on the ejected matter are obtained through electromagneticobservations. We also estimate the mass and spin of the remnants and find themto be in the range $[2.34, 3.38] M_{\odot}$ and $[0.63, 0.82]$ respectively,for our dataset.
