Crays is the collective name given to St. Paul's Cray and St. Mary's Cray in the London Borough of Bromley.
The area, which has been amalgamated into Orpington, is now mostly suburban housing, and features St Mary Cray railway station, a High Street with a small parade of shops (at one time a longer high street, with more shops, than Orpington) and St Mary the Virgin church, after which the village was named. It was originally called South Cray, identifying it as the southernmost settlement on the river.
A dominant feature of St Mary Cray and St Paul's Cray are the industrial estates on Cray Avenue and Sevenoaks Way, home to retail outlets such as PC World, Comet, Land of Leather, Homebase, JJB Sports, MFI, Currys, Carpet Right and Arco. These retailers list their stores as Orpington branches.
