KWSX (1280 AM) is a broadcast radio station in the United States. Licensed to Stockton, California, the station has a sports format and has been owned by iHeartMedia, Inc. and its predecessors since 1996. KWSX broadcasts the national Fox Sports Radio network for most of the week in addition to play-by-play coverage of local college and professional sports teams, including University of the Pacific men's basketball and Stockton Ports.

Founded in 1947 as KXOB, the station had music formats for much of its early history. It was owned by Joseph Gamble Stations for much of the 1950s through 1990s, during which the station changed its call sign to KJOY in 1956 and KJAX in 1989. In 1992, KJAX dropped music to be a full-time news/talk station. The Gamble company sold KJAX in 1996, when the station began the first of several stints simulcasting the talk format of Modesto co-owned station KFIV.

In 1999, the station became KUYL, with a change to a Christian religious format following in 2002. Then in 2005, the station picked up its current KWSX call sign, and in early 2006, KWSX changed its religious format to a conservative talk format simulcast with KFIV. In 2018, KWSX adopted its current sports format.
