Worthing Football Club are an English association football club based in Worthing, West Sussex, currently playing in the Isthmian League Premier Division. The club plays at Woodside Road.
The club was originally formed as Worthing Association Football Club (a name that lasted until 1899) in February 1886 and played friendlies and Sussex Senior Cup ties for the first few years of their existence.
In 1896 the club became founding members of the West Sussex Football League, joining the Senior Division. During their time in the West Sussex league they were league champions on seven occasions. In May 1900 the club absorbed local rivals Worthing Athletic and a year later moved to its current home, then known simply as the Sports Ground, now as Woodside Road. In 1905 another rival team, Worthing Rovers, was also absorbed.
The club's intriguing nickname of "The Rebels" dates from when it resigned from the West Sussex League on a point of principle over a rule change, prior to becoming a founder member of the Sussex County League in 1920. Worthing are also known as "The Mackerel Men", a reference to the three fish prominent on the club crest.
In 1920 Worthing became founder members of the Sussex County League, where once again they won eight league titles, in fact in the twenty seasons prior to World War II they only finished outside the top four on two occasions.
In 1948–49 Worthing joined the Corinthian League but met with little success. In 1963 the Corinthian League disbanded and most of its clubs joined the newly created Athenian League Division One, where Worthing won promotion at the first attempt, although after three seasons in the Premier Division, two successive relegations saw them drop to Division 2.
After managing a return to the top division, Worthing joined the Isthmian League in 1977, initially in Division Two, but by 1983 they had reached the Premier Division under manager Barry Lloyd and in fact finished as runners-up in 1983–84 and 1984–85.
