We discuss diffraction limited observations of M87 in the mid-infrared. Our previous work showed that at N band the nucleus of M87 is dominated by the AGN point-source, but was marginally resolved. Emission from the jet and nucleus were modeled as synchrotron radiation. Here we concentrate on the nucleus, using more recent mid-IR imaging and spectroscopy. We find that a single-component synchrotron model cannot account for the IR continuum seen from the nucleus. We discuss the possibility of dust emission and/or absorption from M87, model the emission line features, and consider implications for AGN unified schemes.
