[abridged] We present point-source catalogs for the 4Ms Chandra DeepField-South (CDF-S), which is the deepest Chandra survey to date and covers anarea of 464.5 arcmin^2. We provide a main source catalog, which contains 740X-ray point sources that are detected with wavdetect at a false-positiveprobability threshold of 1E-5 and also satisfy a binomial-probabilitysource-selection criterion of P<0.004; this approach is designed to maximizethe number of reliable sources detected. A total of 300 main-catalog sourcesare new compared to the previous 2Ms CDF-S main-catalog sources. We alsoprovide a supplementary catalog, which consists of 36 sources that are detectedwith wavdetect at 1E-5, satisfy 0.004< P<0.1, and have an optical counterpartwith R<24. Multiwavelength identifications, basic optical/infrared/radiophotometry, and spectroscopic/photometric redshifts are provided for the X-raysources. Basic analyses of the X-ray and multiwavelength properties of thesources indicate that >75% of the main-catalog sources are AGNs; of the 300 newmain-catalog sources, about 35% are likely normal and starburst galaxies,reflecting the rise of normal and starburst galaxies at the very faint fluxlevels uniquely accessible to the 4Ms CDF-S. Near the center of the 4Ms CDF-S,the observed AGN and galaxy source densities have reached ~9800 and 6900 persquare degree, respectively. The 4 Ms CDF-S reaches on-axis flux limits of~9.1E-18 and 5.5E-17 erg/cm^2/s for the soft and hard bands, respectively. Anincrease in the CDF-S exposure by a factor of ~2-2.5 would provide furthersignificant gains and probe key unexplored discovery space.
