The WTA Tier IV tournaments were Women's Tennis Association tennis fourth-level tournaments held from 1990 until the end of the 2008 season. The line-up of events varied over the years, with tournaments being promoted, demoted or cancelled. Some of the tournaments became Tier V events between 1990 and 1992 and later from 2001 to 2005 before being integrated back into Tier IV.
