General John Proby, 2nd Earl of Carysfort (1780 – 11 June 1855), known as Lord Proby from 1804 to 1828, was a British military commander and Whig politician.

Proby was the second but eldest surviving son of John Proby, 1st Earl of Carysfort, and his wife Elizabeth (née Osbourne), and was educated at Rugby. He gained the courtesy title of Lord Proby when his elder brother died in 1804. He succeeded his father in 1828, inheriting Elton Hall in Huntingdonshire (now in Cambridgeshire).

He was commissioned into the British Army in 1794 and fought in the French Revolutionary Wars. Carysfort was promoted to major-general in 1814, and in that year took part in the ill-fated attack on Bergen op Zoom in the Netherlands.^[1] He was promoted to lieutenant-general in 1830 and to general in 1846.

Apart from his military career he also represented Buckingham in the House of Commons from 1805 to 1806 and Huntingdonshire from 1806 to 1807 and again from 1814 to 1818. Proby was supportive of the British abolitionist movement.^[2]

Lord Carysfort died in June 1855. He never married and was succeeded in the earldom by his younger brother Granville.
