AB - A search is presented for long-lived particles decaying into an oppositely charged lepton pair, μ<sup>+</sup>μ<sup>−</sup>, e<sup>+</sup>e<sup>−</sup>, or e <sup> ± </sup> μ <sup></sup>, that form a vertex within the inner tracking system of the ATLAS detector at the Large Hadron Collider, displaced from the primary proton–proton interaction region. The analysis uses the 140 fb<sup>−1</sup> of Run-2 data collected at s=13 TeV by the ATLAS experiment in 2015–2018. The results of the analysis are interpreted in the context of three benchmark models covering masses from 0.1 to 2.2 TeV and a range of mean proper lifetimes times the speed of light from 1 to 10 000 mm. The first model is a generic Z ′ boson pair-produced by a new heavy scalar, with the Z ′ decaying into lepton pairs. The remaining two models are R -parity violating supersymmetric models in which the lightest neutralino χ˜<inf>1</inf><sup>0</sup> decays into <sup>+</sup><sup><sup>′</sup><sup>−</sup></sup>ν (,<sup>′</sup>=e, μ). The models differ by the mode of production of the χ˜<inf>1</inf><sup>0</sup>, which can be produced via the decay of pairs of gluinos or of pairs of charginos and neutralinos (χ˜<inf>1</inf><sup>±</sup>χ˜<inf>1</inf><sup>0</sup>, χ˜<inf>1</inf><sup>±</sup>χ˜<inf>2</inf><sup>0</sup>, or χ˜<inf>2</inf><sup>0</sup>χ˜<inf>1</inf><sup>0</sup>). Although each benchmark sample includes pair-produced LLPs, only a single vertex is required to be reconstructed. No dilepton displaced v
