Fox Soccer, formerly Fox Soccer Channel & Fox Sports World, was an American television specialty channel specializing in soccer, owned by News Corporation and later 21st Century Fox, that operated from 1997 to 2013. It originally broadcast rugby and Australian rules football, but was strictly devoted to soccer its last years on-air.

Due to Fox consolidating its cable sports rights on the then-new general-interest channels Fox Sports 1 and Fox Sports 2, and following the loss of local television rights to broadcast Premier League soccer events to NBC, Fox Soccer was replaced on September 2, 2013, by FXX, an entertainment sister network to FX. The vast majority of the remaining sports programming from Fox Soccer has been moved to Fox Sports 1 and Fox Sports 2, which launched on August 17, 2013. Fox Soccer Plus, a spin-off channel which launched in 2010, continues to operate.

Launched on November 1, 1997, when it was originally known as Fox Sports World, the channel took its final name February 7, 2005, later dropping the word "channel" from its name on August 1, 2011, Fox Soccer offered its own game programming for United States soccer leagues through arrangements with outside production companies.

Most of Fox Soccer's coverage which originated outside the CONCACAF region (North America, Central America, Caribbean) consisted of picking up international broadcast feeds to which Fox Soccer had the U.S. broadcast rights. The A-League broadcasts were produced by Fox Sports (Australia). The English coverage generally came to Fox Soccer direct from IMG, Input Media and The Media Company, which produce the Premier League and FA Cup/England national team world feed broadcasts and Fox Soccer News reports respectively.

The network's soccer coverage was not limited to game play; Fox Soccer aired reruns of Dream Team, a British soap opera that aired in the UK on Fox Soccer's corporate cousin Sky One until 2007 and focused on a fictional Premiership team. The channel also televised a live soccer talk-show, Fox Football Fone-in, featuring viewer calls and predictions for that weekend's Premier League matches. During the Premier League term, Fox Soccer also produced and aired a couple of studio-based shows surrounding its game coverage.

In 2006, Fox Soccer announced that they had dropped coverage of sports other than soccer. Amongst the leagues dropped were Super Rugby (rugby union), the Australian Football League (the principal Australian rules football league), and the Australian National Rugby League. The Super 14 games resided on Setanta Sports USA until it went off the air in early 2010, while ESPN offers the AFL. In return, Setanta gave Fox Soccer the rights to some national team matches that would not otherwise air live. After Setanta's demise in the US, News Corporation acquired most of Setanta USA's former rights and created the new Fox Soccer Plus as a second broadcast outlet.

Fox Sports World originally filled out its schedule with an eclectic mix of programming; among the sports featured (either in anthology form or actual events) were motorsports (prior to News Corporation's acquisition of SPEED, now Fox Sports 1), cricket, pool, darts, and extreme sports. It also aired the Final Four of the Euroleague in basketball; that league is now more extensively covered by NBA TV. Cricket, pool and darts currently see American coverage on Willow and ONE World Sports, which also now broadcasts some Sky Sports programming.

Until the middle of 2012, the morning hours on non-game days (when the English and European afternoon is timed to in the United States) and some odd afternoon half hours were slotted with paid programming time until additional loops of Fox Soccer News and Sky Sports News were placed in those slots.
