The Spitzer Space Telescope has three science instruments (IRAC, MIPS, and
IRS) that can take images at 3.6, 4.5, 5.8, 8.0, 24, 70, and 160 microns,
spectra over 5--38 microns, and spectral energy distribution over 52--100
microns. The Spitzer archive contains targeted imaging observations for more
than 100 PNe. Spitzer legacy surveys, particularly the GLIMPSE survey of the
Galactic plane, contain additional serendipitous imaging observations of PNe.
Spitzer imaging and spectroscopic observations of PNe allow us to investigate
atomic/molecular line emission and dust continuum from the nebulae as well as
circumstellar dust disks around the central stars. Highlights of Spitzer
observations of PNe are reviewed in this paper.Comment: 8 pages, 7 figures, invited review in IAU Symposium 283, Planetary
