Abstract : Neutrinos are the second most abundant particle in the universe. Since the last 50 years, Neutrino physics has been a source of limelight in modern physics because of the incredible characteristics of this elusive particle. According to the basic postulates of the Standard Model of particle physics neutrinos were assumed to be massless, but the results inferred from the experiments conducted in the past few years in the field of neutrino physics have concluded that neutrinos have a finite mass. In this paper we have discussed the various experiments conducted in the past which have tried to set an experimental limit on the absolute neutrino masses. Further, the future experiments which are expected to bring these limits to the sub eV regime are also discussed.
