Warfleet Creek is a small triangular tidal inlet in the west side of the River Dart estuary in England. It is near Dartmouth, Devon. It has steep rocky sides.

At low tide there is a stony beach with some small rockpools.

The British Underwater Centre was one of the premises along its north side. It had anchorage for boats, and facilities for training in scuba diving and standard diving. It was run by Captain Trevor Hampton who was based there for many years.

The war fleets for which the creek is named are those of the crusades of 1147 and 1190, although the harbour of Dartmouth has seen many others, not least the American fleet en route to Utah beach on D Day.
