  We present 2,241 exoplanet candidates identified with data from the
Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission.
We list these candidates in the TESS Objects of Interest (TOI) Catalog, which
includes both new planet candidates found by TESS and previously-known planets
recovered by TESS observations. We describe the process used to identify TOIs
and investigate the characteristics of the new planet candidates, and discuss
some notable TESS planet discoveries. The TOI Catalog includes an unprecedented
number of small planet candidates around nearby bright stars, which are
well-suited for detailed follow-up observations. The TESS data products for the
Prime Mission (Sectors 1-26), including the TOI Catalog, light curves,
full-frame images, and target pixel files, are publicly available on the
Mikulski Archive for Space Telescopes.
