We present extensive tables of the atomic partition functions (APFs) for nickel ions, Ni I-Ni X. Partition functions are given over wide range of temperature, 10³ K<T<10⁶ K, and lowering of ionization energy (0.001 eV<LIE<5.0 eV), both taken as independent variables. Our APFs take into account all energy levels predicted by quantum mechanics, including autoionization levels. The tables can be applied for computations of model stellar atmospheres and theoretical spectra over very wide range of spectral classes, from the coolest K-M dwarfs up to the hottest main sequence, giant, and white dwarf stars. This include also model spectra of supersoft X-ray sources and accretion discs in interacting binaries. Our tables are available via Internet from Acta Astronomica Archive or http://draco.uni.opole.pl/Halenka.html
