APOGEE is a large-scale survey of the stellar populations of the Milky Way Galaxy, which. One of four surveys making up the third installment of the Sloan Digital Sky Survey (SDSS-III), APOGEE collected high resolution (R = 23,000) H-band spectra of over 140,000 stars from all components of the Galaxy (thin and thick disks, bulge, and halo). Accurate radial velocities and abundances of 15 elements were extracted from APOGEE spectra, and these data will provide fundamental constraints on models for the formation of the Galaxy. I will describe the survey, its main science goals, and present some recent science results. I will conclude by talking about the next incarnation of the survey, APOGEE-2, which started operations in the Fall of 2014. Part of SDSS-IV, APOGEE-2 will increase the original APOGEE sample by a factor of several, and greatly expand its spatial coverage by addition of a Southern component, based at the du Pont 2.5 m telescope in Las Campanas, Chile. The main science goals and current status of APOGEE-2 will be briefly discussed.
