1LHAASO J0249+6022 is an extended very-high-energy γ-ray source discovered by the Large High-Altitude Air Shower Observatory. Based on nearly 16.1 yr of data from the Fermi Large Area Telescope, we report the probable γ-ray emission from 1LHAASO J0249+6022 in the 0.03-1 TeV energy range. The results show that its γ-ray spectrum can be well fitted by a single power law with an index of 1.54 ± 0.17, and integral photon flux is (4.28 ± 1.03) × 10^–11 photons cm^–2 s^–1. We also considered theoretically whether the nonthermal emission could originate from a pulsar wind nebula (PWN) scenario. Assuming that the particles injected into the nebula have a power-law distribution, the resulting spectrum from the inverse Compton scattering is consistent with the detected GeV and TeV γ-ray fluxes. Our study shows that the PWN scenario is reasonable for 1LHAASO J0249+6022.
