We report on observations of the Large Magellanic Cloud with the Fermi Gamma-Ray Space Telescope. The LMC is clearly detected with the Large Area Telescope (LAT) and for the first time the emission is spatially well resolved in gamma-rays. Our observations reveal the massive star forming region 30 Doradus as a bright source of gamma-ray emission in the LMC. The observations furthermore show that the gamma-ray emission correlates little with the gas density of the LMC. Implications of this finding will be discussed.
