In this letter we report the observation of extremely large non-saturatinglinear magnetoresistance (MR) in Antimony(Sb) crystal. An extremely largemagnetoresistance (XMR) of 43000% at 2K and large unsaturating MR$\sim\ $70% atroom temperature is observed at the magnetic field of 9T. Hall measurementsreveal a very high mobility $\sim\ $3.8 x 10$^{4}$ cm$^{2}$/Vs of chargecarriers and strong temperature dependence of carrier concentration andmobility. The respective scaling of MR and crossover field (B$_{c}$) fromquadratic to linear MR with mobility and inverse of mobility describes theclassical origin of large linear MR in this crystal as suggested by Parish andLittlewood (PL) model for disordered systems.
