The WTA Tier IV tournaments were Women's Tennis Association 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.[1]

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.
