The Triumphs of Oriana is a book of English madrigals, compiled and published in 1601 by Thomas Morley, which first edition has 25 pieces by 23 composers for 5 and 6 voices. The first 14 madrigals are for 5vv, the last 11 for 6vv. It was said to have been made to honour Queen Elizabeth I. Every madrigal in the collection contains the following couplet at the end: “Then sang the shepherds and nymphs of Diana: long live fair Oriana” though some of the composers wrote variants of this refrain.

Thomas Morley was an English composer, theorist, singer and organist of the Renaissance. He was one of the foremost members of the English Madrigal School. Referring to the strong Italian influence on the English madrigal, The New Grove Dictionary of Music and Musicians states that Morley was "chiefly responsible for grafting the Italian shoot on to the native stock and initiating the curiously brief but brilliant flowering of the madrigal that constitutes one of the most colourful episodes in the history of English music."
