The 27-year-old has been strongly linked with a move to the Tigers over the last week or so, with boss Steve Bruce keen on signing the midfielder.
That deal has now been completed, with the Senegal international believed to have agreed a three-year contract.
Diame joined West Ham from Wigan Athletic in 2012.
