We describe the first data release from the Spitzer-IRAC Equatorial Survey (SpIES); a large-area survey of similar to 115 deg(2) in the Equatorial SDSS Stripe 82 field using Spitzer during its "warm" mission phase. SpIES was designed to probe sufficient volume to perform measurements of quasar clustering and the luminosity function at z >= 3 to test various models for "feedback" from active galactic nuclei (AGNs). Additionally, the wide range of available multi-wavelength, multi-epoch ancillary data enables SpIES to identify both high-redshift (z >= 5) quasars as well as obscured quasars missed by optical surveys. SpIES achieves 5 sigma depths of 6.13 mu Jy (21.93 AB magnitude) and 5.75 mu Jy (22.0 AB magnitude) at 3.6 and 4.5 mu m, respectively-depths significantly fainter than the Wide-field Infrared Survey Explorer (WISE). We show that the SpIES survey recovers a much larger fraction of spectroscopically confirmed quasars (similar to 98%) in Stripe 82 than are recovered by WISE (similar to 55%). This depth is especially powerful at high-redshift (z >= 3.5), where SpIES recovers 94% of confirmed quasars, whereas WISE only recovers 25%. Here we define the SpIES survey parameters and describe the image processing, source extraction, and catalog production methods used to analyze the SpIES data. In addition to this survey paper, we release 234 images created by the SpIES team and three detection catalogs: a 3.6 mu m. only detection catalog containing similar to 6.1 million sources, a 4.5 mu m. only detection catalog containing similar to 6.5 million sources, and a dual-band detection catalog containing similar to 5.4 million sources.
