We report on the detection of GeV gamma-ray emission spatially coincident with the binary system PSR B1259-63 with the Large Area Telescope (LAT), one of the two instruments on board the Fermi Gamma-ray Space Telescope. Preliminary analysis of 32 days of Fermi-LAT data in the region around the system in the period 2010-11-17 to 2010-12-19 UTC gives a flux (E>100 MeV) of 1.2 +/- 0.6 x 10^-7 ph cm^- 2 s^- 1 and a photon index of 2.2 +/- 0.2....
