We report experimental hyperfine structure constants of levels in the neutral manganese atom, measured using Fourier transform spectroscopy of hollow cathode discharges. In total, 208 spectral lines of astrophysical interest have been analyzed to obtain hyperfine structure constants for 106 levels in Mn I, of which 67 have no previous hyperfine structure measurements. The uncertainties in the magnetic dipole constants, A, are between 1 x 10(-4) and 5 x 10(-4) cm(-1). Hyperfine structure constants for an additional 18 levels compiled from the literature are also given.
