  Many new physics models, e.g., leptoquarks, extra dimensions, extended Higgs
sectors, supersymmetric theories, and dark sector extensions, are expected to
manifest themselves in the final states with hadronic jets. Novel experimental
techniques, including a dedicated scouting trigger stream and advanced machine
learning techniques can be employed to identify such signals. This talk
presents searches in CMS for new phenomena in the final states that include
jets, focusing on the most recent results obtained using the full Run-II
data-set collected at the LHC.
