Alfred Tennyson, 1st Baron Tennyson, FRS (6 August 1809 – 6 October 1892), much better known as "Alfred, Lord Tennyson," was Poet Laureate of the United Kingdom during much of Queen Victoria's reign and remains one of the most popular poets in the English language.

Tennyson excelled at penning short lyrics, "In the valley of Cauteretz", "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 (Oenone, Ulysses, Tithonus), as well as works based on Arthurian legends (Idylls of the King, The Lady of Shalott, Sir Galahad). 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.

Tennyson wrote a number of phrases that 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", "Knowledge comes, but Wisdom lingers", and "The old order changeth, yielding place to new". He is the second most frequently quoted writer in The Oxford Dictionary of Quotations after Shakespeare.
