A wide variety of physics models can give rise to particles with long lifetimes. While the ATLAS and CMS experiments at the LHC were designed primarily to identify promptly decaying particles, both collaborations host multiple analyses targeting the decay of hypothetical particles with macroscopic decay lengths. This proceeding considers two such analyses. The first, an ATLAS analysis, identifies pairs of displaced leptons which do not share a vertex. The second, a CMS analysis, targets clusters in the muon system endcap with high hit multiplicity. The strategy and results of each analysis are reported.
