Richard Cavendish (died c. 1601) of Trimley St Martin, Suffolk, and of Nottinghamshire was an English courtier and politician.
[1] He was the second son of Sir Richard Gernon, alias Cavendish, by his wife Beatrice Gould, and was a native of Suffolk.
[2] In 1568 and 1569 Cavendish was engaged in conveying to Mary, Queen of Scots letters and tokens to further her marriage with Thomas Howard, 4th Duke of Norfolk; in 1569 the earls of Shrewsbury and Huntingdon in the latter year tried to capture Cavendish and prevent the circulation of his writings.
To the parliament which met 8 May 1572 he was returned for Denbigh Boroughs, in opposition to the wishes of the Earl of Leicester.
Cavendish had suggested to the Queen that it was in her power to create a new office for making out all writs of supersedeas in the Court of Common Pleas; and she granted the post to him for a number of years.
