This talk presents the latest jet measurements in 5.02 TeV Pb+Pb collisions with the ATLAS Experiment at the LHC. Jets are direct probes of the quark-gluon plasma produced in heavy-ion collisions and studying how they are modified in the heavy-ion collisions compared to the pp collisions provides insight into their interactions with this QCD medium. The latest jet results from ATLAS shown in this talk include measurements of nuclear modification factor of jets, jet fragmentation functions, the momentum and angular dependence of charged particle yields within and around jets, and the correlations of jets with direct photons. The presented measurements are also directly compared to state of the art theoretical models and provide important information to understand the strength and mechanism of the jet quenching. Further, this talk presents ATLAS results on dijet production in p+Pb collision that help to understand the partonic structure of heavy nuclei, and serve as a constraint on the initial state of Pb+Pb collisions.
