Abstract: This chapter of the Gaia DR3 documentation describes the processing of the source characterisation in Gaia DR3, based on mean BP/RP and RVS spectra, astrometry, and photometry. Characterisation implies stellar and extragalactic class probabilities, object-type labels, and parametrisations with associated uncertainties (1D data products). Gaia DR3 also includes multi-dimensional data products such as a 2D extinction map and a self-organising map of outliers.
