The football teams of the club were originally organised by Yuen Long District Sports Association (Chinese: 元朗區體育會).

In 2013, Yuen Long Football Club was established as a private entity, separate from the district sports association.

With the creation of the Hong Kong Third District Division, Yuen Long was reformed and entered the league in 2003.

From 2013 to 2015, they were branded as I Sky Yuen Long due to the sponsorship from Simsen International Corporation Limited.

However, despite winning silverware, Sun Bus dropped their sponsorship of the club at the end of the season.
