The late-time tail behaviors of massive scalar fields are examined analytically in the background of a black hole with a global monopole. It is found that the presence of a solid deficit angle in the background metric makes the massive scalar fields decay faster in the intermediate times. However, the asymptotically late-time tail is not affected and it has the same decay rate of $t^{ -5/6}$ as in the Schwarzschild and nearly extreme Reissner-Nordstr\"{ o}m backgrounds.
