We present a spectroscopic survey using the MMT Hectospec fiber spectrograph of 24 µm sources selected with the Spitzer Space Telescope in the Spitzer First Look Survey. We report 1296 new redshifts for 24 µm sources, including 599 with f_ν(24 µm)≥1 mJy. Combined with 291 additional redshifts for sources from the Sloan Digital Sky Survey (SDSS), our observing program was highly efficient and is ∼90% complete for i≤21 mag and f_ν(24 µm)≥1 mJy and 35% complete for i≤20.5 mag and 0.3 mJy≤f_ν(24 µm)<1.0 mJy. Our Hectospec survey includes 1078 and 168 objects spectroscopically classified as galaxies and QSOs, respectively. Combining the Hectospec and SDSS samples, we find 24 µm-selected galaxies to z_gal≤0.98 and QSOs to z_QSO≤3.6, with mean redshifts of <z_gal≥0.27 and <z_QSO≥1.1. As part of this publication, we include the redshift catalogs and the reduced spectra; these are also available through the NASA/IPAC Infrared Science Archive.
