We present a photometric catalog for Spitzer Space Telescope warm mission observations of the North Ecliptic Pole (NEP; centered at R.A.=18h00m00s, Decl.=66d33m38s.552). The observations are conducted with IRAC in 3.6 μm and 4.5 μm bands over an area of 7.04 deg2 reaching 1σ depths of 1.29 μJy and 0.79 μJy in the 3.6 μm and 4.5 μm bands respectively. The photometric catalog contains 380,858 sources with 3.6 μm and 4.5 μm band photometry over the full-depth NEP mosaic. Point source completeness simulations show that the catalog is 80% complete down to 19.7 AB. The accompanying catalog can be utilized in constraining the physical properties of extra-galactic objects, studying the AGN population, measuring the infrared colors of stellar objects, and studying the extra-galactic infrared background light.
