Measurements of multiboson production at the LHC probe the electroweak gauge structure of the Standard Model for contributions from anomalous couplings. Processes involving quartic gauge-boson self-interactions have only become experimentally accessible with the LHC Run-2 data through the study of electroweak diboson and triboson production. In this seminar, recent ATLAS results on the measurement of electroweak production of a Zgamma pair in association with two jets and the first observation of three W boson production are presented. Moreover, precise boson and diboson differential cross-section measurements are interpreted in a combined  Effective Field Theory analysis, allowing to systematically probe gauge boson self-interactions.
