We provide here tables of stellar limb-darkening coefficients (LDCs) for theAriel ESA M4 space mission. These tables include LDCs corresponding todifferent wavelength bins and white bands for the NIRSpec, AIRS-Ch0 andAIRS-Ch1 spectrographs, and those corresponding to the VISPhot, FGS1 and FGS2photometers. The LDCs are calculated with the open-source software ExoTETHySfor three complete grids of stellar atmosphere models obtained with the ATLAS9and PHOENIX codes. The three model grids are complementary, as the PHOENIX codeadopts more modern input physics and spherical geometry, while the modelscalculated with ATLAS9 cover wider ranges of stellar parameters. The LDCsobtained from corresponding models in the ATLAS9 and PHOENIX grids are comparedin the main text. All together the models cover the following ranges ineffective temperature ($1\,500 \, K \le T_{\mbox{eff}} \le 50\,000 \, K$),surface gravity (0.0 dex $\le \log{g} \le 6.0$ dex), and metallicity ($-5.0 \le[M/H] \le 1.0$).
