Scroby Sands was one of the first off-shore wind farms in the United Kingdom, and is situated 2.5 kilometres (1.6 miles) off the coast of Norfolk, near Great Yarmouth in the UK. It is currently owned and operated by E.ON, an international power company based in France.

The site was commissioned in 2004, and consists of thirty wind turbines, which are capable of generating a total of 60 megawatts, enough to power over 40,000 homes.

The turbines stand in water up to 20 metres (66 feet) deep and their central pivot is 60 metres (200 feet) above sea level; each turbine is three bladed, with each blade 40 metres (130 feet) in length.

There is an on shore visitor centre in Great Yarmouth which attracts many tourists.
