  Leptoquarks (LQ) are predicted by many new physics theories to describe the
similarities between the lepton and quark sectors of the Standard Model and
offer an attractive potential explanation for the lepton flavour anomalies
observed at LHCb and flavour factories. The ATLAS experiment has a broad
program of direct searches for Leptoquarks, coupling to the first-, second- or
third-generation particles. The most recent 13 TeV results on the searches for
Leptoquarks and contact interactions with the ATLAS detector are reviewed,
covering flavour-diagonal and cross-generational final states.
