Cavendish was the second son of William Cavendish, 1st Earl of Devonshire, by his first wife Anne Keighley.
He was educated by Thomas Hobbes, the philosopher, who lived at Chatsworth as his private tutor for many years.
He was knighted at Whitehall in 1609. He was accompanied by Hobbes on the Grand Tour from about 1610, when he visited France and Italy before his coming of age. He became Lord Lieutenant of Derbyshire in 1619.
In 1621 he was re-elected Member of Parliament for Derbyshire.
In April 1622 he introduced to audiences with the king Schwarzenburg, ambassador from the Emperor Ferdinand, Valerssio from Venice, and d"Arsennes and Joachimi from the United Provinces. He was re-elected Member of Parliament for Derbyshire in 1624 and 1625.
In 1625 he was present at Charles I"s marriage with Henrietta Maria. He was high bailiff of Tutbury in 1626 and was re-elected Member of Parliament for Derbyshire in 1626, until the death of his father early in 1626 gave him a seat in the House of Lords.
In the Lords, he resisted George Villiers, 1st Duke of Buckingham"s attempt to find a treasonable meaning on a speech of Sir Dudley Digges (13 May 1626).
Cavendish"s spending strained his resources, and he procured a private act of parliament to enable him to sell some of the entailed estates in discharge of his debts in 1628. His London house was in Bishopsgate, on the site afterwards occupied by Devonshire Square. Cavendish died at his London house, from over-indulgence it was said, at the age of about 35 and was buried in Allhallows Church, Derby.
Cavendish married Christian(a) Bruce, daughter of Edward Bruce, 1st Lord Kinloss, on 10 April 1608.

Anne Cavendish (c 1611–?), married Robert Rich, 3rd Earl of Warwick and had issue. William Cavendish, 3rd Earl of Devonshire (1617–1684)
