I will summarize recent results from mid-infrared observations of cataclysmic variables obtained with the Spitzer Space Telescope. In general, these observations have revealed mid-infrared excesses, above the level expected from the stellar components and accretion disk, in numerous systems. This excess can be modeled as originating from circumstellar and/or circumbinary dust. I will present an overview of spectral energy distributions spanning wavelengths from the UV (0.1 microns) out to the mid-IR (24 microns), mid-IR (4.5 and 8 microns) light curves of disk-accreting and magnetic cataclysmic variables, and Spitzer Infrared Spectrograph spectra of several systems. Physically realistic models constructed to reproduce these data indicate that the mid-infrared luminosity of many cataclysmic variables is dominated by emission from warm (T < 1000 K) dust.
