Basil Willett Charles Hood (5 April 1864 – 7 August 1917) was a British dramatist and lyricist, perhaps best known for writing the libretti of half a dozen Savoy Operas and for his English adaptations of operettas, including The Merry Widow.

He embarked on a career in the British Army, rising to the rank of captain, while writing theatrical pieces in his spare time. After some modest success, Hood and his collaborator, the composer Walter Slaughter, had a major hit with their long-running show, Gentleman Joe, in 1895. Another long-running success was The French Maid (1896). Hood then resigned from the army to pursue his career as a librettist full-time. With Arthur Sullivan and then Edward German, he wrote several well-received pieces for the Savoy Theatre, including The Rose of Persia (1899), The Emerald Isle (1901), Merrie England (1902) and A Princess of Kensington (1903).

After comic opera went out of fashion, Hood turned to Edwardian musical comedy, writing lyrics for The Belle of Mayfair (1906) and The Girls of Gottenberg (1907), among others. He then found his greatest success with adaptations of continental operettas for the impresario George Edwardes, writing English versions of such works as (1907), The Dollar Princess (1908), A Waltz Dream (1908) and The Count of Luxembourg (1911), among others, sometimes drastically rewriting the book and lyrics. At the outbreak of World War I, he took up a demanding post in the British War Office, which is believed to have contributed to his early death.
