We present sub-arcsecond resolution imaging of nearby low-luminosity AGNs at near- and mid-infrared wavelengths using the NIRC and LWS instruments on the Keck I telescope. Of the 17 objects surveyed in the near-infrared, about 50% of them have an unresolved nuclear source. Fourteen of the objects were reobserved at 12.5 microns and of these, 12 were found to have a mid-infrared source associated with them. We use the near- to mid-infrared spectral slope in conjunction with radio and X-ray observations to assess the origin of the infrared emission, estimate the amount of dust in the nuclear regions, and constrain the nature of the accretion physics around the nuclear black hole.
