Byfleet is an inland island surrounded by waterways and a village of medieval origin that is today the most distant but contiguous suburb of the large town of Woking in Surrey, England. Subsequently, residents are often referred to as 'Islanders'. Part, particularly the Sanway area, forms Metropolitan Green Belt agricultural fields or sports grounds. Byfleet takes up the far east of the borough and much of the land is within the widest gap between the Wey Navigation and the River Wey. Its western boundary is the M25 motorway and a major junction with the A3 .
July 2012 marked a historic moment in Byfleet's history, becoming a host of the men's and women's cycling road races for the 2012 Summer Olympics Games. Though more common for Surrey settlements of its size which are outside the M25, Byfleet is not a post town, and is therefore, when correctly addressed by post, a subsidiary to its offshoot with a similar population, West Byfleet.
