The Isle of Wight Festival is a music festival which takes place every year on the Isle of Wight in England. It was originally held from 1968 to 1970.

The 1970 event was by far the largest and most famous of these early festivals and the unexpectedly high attendance levels led, in 1971, to Parliament passing the "Isle of Wight Act" preventing gatherings of more than 5,000 people on the island without a special licence.

The event was revived in 2002 at Seaclose Park, a recreation ground on the outskirts of Newport. It has been held annually since that year, progressively expanding.
