The Seven Sisters are a series of chalk sea cliffs on the English Channel coast, and are a stretch of the sea-eroded section of the South Downs range of hills, in the county of East Sussex, in south-east England.

The Seven Sisters cliffs run between the mouth of the River Cuckmere near Seaford, and the chalk headland of Beachy Head outside of Eastbourne.

The dips or swales that separate each of the seven crests from the next are the remnants of dry valleys in the chalk South Downs which are being gradually eroded by the sea.

[4] The Seven Sisters are seen in the background of the Quidditch World Cup in the 2005 film Harry Potter and the Goblet of Fire, and also when Slartibartfast is showing Arthur Dent the "new" Earth in The Hitchhiker's Guide to the Galaxy, released the same year.

The Netflix series Anatomy of a Scandal had shots of the Seven Sisters Cliffs that featured Sienna Miller and Rupert Friend.
