Spin transport is the key process for the operation of spinbased devices. Here the recent progress of spin transport in antiferromagnetic insulators (AFMI) is briefed. The observations of the temperature dependence of spin transmission, spin current switching in AFMI and the negative spin Hall magnetoresistance are discussed. The challenges for developing the functionality of antiferromagnetic insulator as well as the unresolved problems from the experimental observations are also discussed.
