The recent detection by the Fermi γ-ray space telescope of high-energy γ-rays from the radio galaxy NGC1275 makes the observation of the very high energy (VHE: E>100GeV) part of its broadband spectrum particularly interesting, especially for the understanding of active galactic nuclei with misaligned multi-structured jets. The radio galaxy NGC 1275 was recently observed by VERITAS at energies above 100GeV for about 8hr. No VHE γ-ray emission was detected by VERITAS from NGC 1275. A 99% confidence level upper limit of 2.1% of the Crab Nebula flux level is obtained at the decorrelation energy of approximately 340GeV, corresponding to 19% of the power-law extrapolation of the Fermi Large Area Telescope result.
