Supersymmetry (SUSY) is one of the most relevant scenarios of new physics searched for at the CERN Large Hadron Collider (LHC). In this contribution, the principal search strategies employed by the ATLAS and CMS experiments are outlined and the most recent results for analyses targeting SUSY discovery are presented. A wide range of signatures are covered motivated by various theoretical scenarios and topologies: strong production, third-generation fermions, electroweak production, $R$-parity violation and long-lived particles. Most results presented here are based on the full Run 2 dataset at $\sqrt{s} = 13$ TeV centre-of-mass energy by each experiment at the LHC.
