The WTA Tier IV tournaments were Women's Tennis Association tennis fourth-level tournaments held from 1988 until 2008 season. The line-up of events varied over the years, with tournaments being promoted, demoted or cancelled. The series resulted from a reform of the WTA tour in 1988, offering more prize money for winners. Some of the tournaments became Tier V events between 1988 and 1992 and later from 2001 to 2005 before being integrated back into Tier IV.

From 2009 WTA Tour, WTA changed the tournament categories, so that most of the Tier III and Tier IV tournaments from 2008 were in one category, WTA International tournaments.
