John William Montagu, 7th Earl of Sandwich PC (8 November 1811 – 3 March 1884), styled Viscount Hinchingbrooke from 1814 to 1818, was a British peer and Conservative politician. He served under Lord Derby as Captain of the Honourable Corps of Gentlemen-at-Arms in 1852 and as Master of the Buckhounds between 1858 and 1859.

Montagu was the son of George Montagu, 6th Earl of Sandwich, and his wife Lady Louisa Mary Ann Julia Harriett, daughter of Armar Lowry-Corry, 1st Earl Belmore. He succeeded his father in the earldom in 1818 at the age of six. He was educated at Eton and Trinity College, Cambridge. While at Cambridge he played two first-class matches for the Cambridge University Cricket Club.

Lord Sandwich served in the Earl of Derby's first administration as Captain of the Honourable Corps of Gentlemen-at-Arms from February to December 1852 and was admitted to the Privy Council the same year. When the Conservatives returned to power under Derby in 1858 Sandwich was appointed Master of the Buckhounds, an office he retained until the government fell the following year. Apart from his political career he was also Lord-Lieutenant of Huntingdonshire between 1841 and 1884.
