  IGR~J19149+1036 is a high mass X-ray binary detected by INTEGRAL in 2011 in
the hard X-ray domain. We have analyzed the BAT survey data of the first 103
months of the Swift mission detecting this source at a significance level of
~30 standard deviations. The timing analysis on the long term BAT light curve
reveals the presence of a strong sinusoidal intensity modulation of 22.25+/-
0.05 d, that we interpret as the orbital period of this binary system.
  A broad band (0.3-150 keV) spectral analysis was performed combining the BAT
spectrum and the XRT spectra from the pointed follow up observations. The
spectrum is adequately modeled with an absorbed power law with a high energy
cutoff at ~24 keV and an absorption cyclotron feature at ~31 keV. Correcting
for the gravitational redshift, the inferred magnetic field at the neutron star
surface is B_surf ~ 3.6 x 10^12 gauss.
