The Spitzer Space Telescope has been a remarkably successful platform for studies of exoplanet atmospheres, with notable results including the first detection of the light emitted by an extrasolar planet (Deming et al. 2005, Charbonneau et al. 2005), the first spectrum of an extrasolar planet (Richardson et al. 2007, Grillmair et al. 2007), and the first map of the flux distribution across the surface of an extrasolar planet (Knutson et al. 2007). These observations have allowed us to characterize the pressure-temperature profiles, chemistry, clouds, and circulation patterns of a select subset of the massive, close-in planets known as hot Jupiters, along with the hot Saturn HD 149026b and the cooler Neptune-mass planet GJ 436b. In my talk I will review the current status of Spitzer observations of transiting planets at the end of the cryogenic mission and look ahead to the observations planned for the two-year warm mission, which will begin this summer after the last of Spitzer's cryogen is exhausted.
