Utilizing the LHAASO-WCDA real-time alert system, we hereby report the detection of a TeV gamma-ray flare originating from the galaxy IC310. LHAASO-WCDA observed a gamma-ray flux enhancement from the radio galaxy commencing at MJD 60375.20. By MJD 60376.56, the accumulated significance reached 7.2 standard deviations, with a flux of approximately 0.5 Crab Unit above 1 TeV. LHAASO is a multi-purpose Extensive Air Shower (EAS) array designed to detect air showers induced by gamma-rays and cosmic rays across a wide energy range, spanning from sub-TeV to beyond 1 PeV.
