Sir Richard Dyer of Staughton (died 1605), was an English courtier, soldier, and landowner.
Dyer married Mary or Marie Fitzwilliam (c. 1556-1601), a daughter of Sir William Fitzwilliam and Anne or Agnes Sidney (1523-1602), a daughter of Sir William Sidney of Penshurst Place and Anne Pakenham.
In June 1586 Sir Philip Sidney recommended "his cousin" Sir Richard Dyer as "very valiant" to Francis Walsingham; "I beseech you both countenance and favour him".
[2] Dyer was said to be at Tilbury in 1588, and Queen Elizabeth is supposed to have visited Place House.
There is a double monument to Sir James Dyer and his wife Margaret Barrowe and Sir Richard Dyer and Mary Fitzwilliam in the church at Great Staughton.
