George Stevens Byng, 2nd Earl of Strafford, PC (8 June 1806 – 29 October 1886), styled Viscount Enfield between 1847 and 1860, of Wrotham Park in Middlesex (now Hertfordshire) and of 5 St James's Square, London, was a British peer and Whig politician.

Byng was the eldest son of Field Marshal John Byng, 1st Earl of Strafford (1772–1860) by his first wife, Mary Mackenzie.^[1]

In 1822, after graduating from the Royal Military College, Byng joined the 29th Regiment of Foot as an ensign by purchase. In 1825 he transferred to the 85th Regiment of Foot as a lieutenant and was promoted to captain in 1826,^{[citation needed]} in which rank he served in the 60th Rifles. In 1837, after he had begun his political career, he was appointed Lieutenant-Colonel of the part-time Royal West Middlesex Militia.^[2] On the death of the regiment's colonel in 1844 Byng succeeded to the command. His eldest son, the Hon George Byng, was commissioned as his lt-col on 30 October 1853. He retired from the command and became the regiment's Honorary Colonel on 5 December 1859.^[3]

Byng's political career began in 1830 when he was elected as a Member of Parliament for Milborne Port,^[4] a seat he briefly held before taking the post of Comptroller of the Household to the Lord-Lieutenant of Ireland (his father-in-law, Lord Anglesey), less than a year later.^{[citation needed]} When his former co-MP, William Sturges-Bourne resigned his seat a few weeks later, Byng returned to his former seat and held it until the Great Reform Bill of 1832 abolished the constituency.^[4] From 1834 he was MP for the new constituency of Chatham, a seat he held until 1835 and again from 1837 to 1852.^[5] He served under Lord Melbourne as a Lord of the Treasury between June and November 1834.

According to the Legacies of British Slave-Ownership at the University College London, Strafford made an unsuccessful claim for compensation in the aftermath of the Slavery Abolition Act 1833 with the Slave Compensation Act 1837.^[6]

Between 1836 and 1837 he represented Poole in parliament.^[7] He again served under Lord Melbourne as Comptroller of the Household between 1835^[8] and 1841^[9] and as Treasurer of the Household between June^[9] and August 1841^[10] and was sworn of the Privy Council in 1835.^[11] When Lord John Russell became Prime Minister in 1846, Byng was appointed Joint Secretary to the Board of Control, a post he retained until 1847.

After losing his parliamentary seat in 1852, Byng was summoned to the House of Lords through a writ of acceleration in his father's barony of Strafford a year later^[12] and inherited his father's earldom in 1860.

Byng married twice:
