We report stellar parameters for three massive stars in the Cygnus OB2 Association: MT216, MT234, and MT485. By comparing spectra from the Cygnus OB2 Radial Velocity Survey to Tlusty model spectra, we determined the best fit effective temperature (Tef f ), surface gravity (log g), and observed rotational velocity (v sin i). We calculated the χ2 error for each model, and then used the best fit parameters to determine the spectroscopic mass of each star.
