A measurement of the production of vector bottomonium states, ϒ(1S), ϒ(2S), and ϒ(3S), in Pb + Pb and pp collisions at a center-of-mass energy per nucleon pair of 5.02 TeV is presented. The data correspond to integrated luminosities of 1.38 nb of Pb + Pb data collected in 2018, 0.44 nb of Pb + Pb data collected in 2015, and 0.26 fb of pp data collected in 2017 by the ATLAS detector at the Large Hadron Collider. The measurements are performed in the dimuon decay channel for transverse momentum p < 30 GeV, absolute rapidity |y| < 1.5, and Pb + Pb event centrality 0-80%.
