Hildebrand Jacob (1692 or 1693–1739) was a British poet and playwright, whose major works include the epic poem Brutus the Trojan and the tragic verse drama The Fatal Constancy.
Following his father, Hildebrand served in the army until at least 1715, then in 1717 he married Meriel, daughter of another baronet, Sir John Bland of Kippax-Park, Yorkshire.
He also wrote comedies: The Nest of Plays (1738) comprised The Prodigal Reform'd, The Happy Constancy, and The Trial of Conjugal Love.
Jacob produced a number of bawdy works, probably including The Curious Maid (1720), although this is sometimes attributed to Matthew Prior (1664–1721).
