Deptford is an area on the south bank of the River Thames in southeast London, within the London Borough of Lewisham. It is named after a ford of the River Ravensbourne. From the mid 16th century to the late 19th it was home to Deptford Dockyard, the first of the Royal Dockyards. This was a major shipbuilding dock and attracted Peter the Great to come and study shipbuilding. Deptford and the docks are associated with the knighting of Sir Francis Drake by Queen Elizabeth I aboard the Golden Hind, the legend of Sir Walter Raleigh laying down his cape for Elizabeth, Captain James Cook's third voyage aboard HMS Resolution, and the mysterious apparent murder of Christopher Marlowe in a house along Deptford Strand.
Though Deptford began as two small communities, one at the ford, and the other a fishing village on the Thames, Deptford's history and population has been mainly associated with the docks established by Henry VIII. The two communities grew together and flourished during the period when the docks were the main administrative centre of the Royal Navy, and some grand houses like Sayes Court, home to diarist John Evelyn, and Stone House on Lewisham Way, were erected. The area declined as first the Royal Navy moved out, and then the commercial docks themselves declined until the last dock, Convoys Wharf, closed in 2000.
A Metropolitan Borough of Deptford existed from 1900 until 1965, when the area became part of the newly created London Borough of Lewisham.
Deptford took its name from a ford across the Ravensbourne (near what is now Deptford Bridge DLR station) along the route of the Celtic trackway which was later paved by the Romans and developed into the medieval Watling Street. The modern name is a corruption of "deep ford".
Deptford was part of the pilgrimage route from London to Canterbury used by the pilgrims in Chaucer's Canterbury Tales, and is mentioned in the prologue to "The Reeve's Tale".
