We study Hausdorff dimension of boundary singular set for suitable weak solutions of the incompressible Navier-Stokes equations. Like  for suitable weak solution in the interior, logarithmic improvement of Hausdorff dimension is proved. The pressure estimate of the inhomogeneous Stokes equations by Green potential due to Solonnikov  is important.
