The Streatfeilds, Streatfields or Stretfields are an aristocratic English family of the landed gentry, from Chiddingstone, Kent. The family are traceable to the early 16th century and are a possible cadet branch of the Noble House of Stratford. They were significant landowners in Sussex, Surrey and Kent, and instrumental in shaping those counties throughout the 17th and 18th centuries. From the early 16th century until 1900 the family seat was Chiddingstone Castle. The family later sold the castle to Lord Astor in 1938.
