New particles may be produced at the LHC with very high boost, for instance if they result from the decay of a heavier resonance. If these boosted particles decay hadronically then their signature is a single fat jet, perhaps with unusual substructure. I will discuss new techniques to search for such boosted resonances, whether their properties are predicted by existing models or if they are completely unexpected. This will make use of recent advances in jet substructure and machine learning.
