We report on observations of the giant ellipitical galaxy M87 in the Virgo Cluster during the XMM-Newton performance verification phase, with EPIC-MOS, EPIC-pn and Optical Monitor instruments. With the energy sensitive imaging instruments MOS and pn we obtain the first spatially constrained X-ray spectra of the nucleus of M87, and find it to be well fit by a power law with a slope of ~.2, with no significant thermal emission contributing to the spectrum. A component of the M87 jet is also detected and well fit by a power law with slope ~.4. The good photon statistics of MOS and pn allow a detailed analysis of the radial temperature and abundance distributions of 6 elements. The temperature structure found are in good agreement with previous observations with ASCA and BeppoSAX. There is no indication of a multi-temperature structure for radii \ge2'. An apparent sharp metal abundance drop at radius smaller than 1' is probably due to resonant line scattering.
