We present the Spitzer Data Fusion, a database incorporating far-ultraviolet to far-infrared flux measurements as well as photometric and spectroscopic redshifts for 4.4 million IRAC-selected sources detected over 8 extragalactic fields covering 65deg^2^ observed by the Spitzer Space Telescope in all its seven IRAC1234 and MIPS123 bands during its cryogenic mission. The catalogs are publicly available at: https://www.mattiavaccari.net/df https://zenodo.org/record/6120913
