I will talk about the recent computation of three loop jet functions (arXiv:1805.02637) in perturbative QCD. These results have been extracted from the known three loop coefficient functions for deep-inelastic scattering via the exchange of a virtual photon that couples to quarks or a scalar that couples to gluons and employing renormalization group invariance and factorization theorem. We obtain both the quark and the gluon jet functions up to three loop level. These jet functions being universal ingredients in the SCET framework, will play an important role in the phenomenological studies at the LHC, such as resummation of jet observables and also in subtraction methods.
