Alfred Tennyson, 1st Baron Tennyson, (6 August 1809 – 6 October 1892) was Poet Laureate of Great Britain and Ireland during much of Queen Victoria's reign and remains one of the most popular British poets.

Tennyson excelled at penning short lyrics, such as "Break, Break, Break", "The Charge of the Light Brigade", "Tears, Idle Tears" and "Crossing the Bar". Much of his verse was based on classical mythological themes, such as Ulysses, although In Memoriam A.H.H. was written to commemorate his best friend Arthur Hallam, a fellow poet and fellow student at Trinity College, Cambridge, who was engaged to Tennyson's sister, but died from a brain haemorrhage before they could marry. Tennyson also wrote some notable blank verse including Idylls of the King, "Ulysses", and "Tithonus". During his career, Tennyson attempted drama, but his plays enjoyed little success.

A number of phrases from Tennyson's work have become commonplaces of the English language, including "Nature, red in tooth and claw", "'Tis better to have loved and lost / Than never to have loved at all", "Theirs not to reason why, / Theirs but to do and die", "My strength is as the strength of ten, / Because my heart is pure", "To strive, to seek, to find, and not to yield", "Knowledge comes, but Wisdom lingers", and "The old order changeth, yielding place to new". He is the ninth most frequently quoted writer in The Oxford Dictionary of Quotations.
