Anthony Warlow AM (born 18 November 1961) is an Australian musical theatre performer, noted for his character acting and considerable vocal range.

He has been honoured as an Australian National Treasure and his achievements have been acknowledged with his investiture as a Member of the Order of Australia (AM) for his services to the performing arts.

Warlow's notable musical theatre roles include lead roles in The Phantom of the Opera (as The Phantom), The Secret Garden (as Archibald Craven), Annie (as Daddy Warbucks), Guys and Dolls (as Sky Masterson), My Fair Lady (as Henry Higgins), Jekyll & Hyde (original Gothic thriller cast recording and, for the 25th anniversary, as Dr Henry Jekyll / Edward Hyde), Man of La Mancha (as Don Quixote), A Little Night Music (as Frederik Egerman), Sweeney Todd: The Demon Barber of Fleet Street (as Sweeney Todd), as well as a significant supporting role in Les Misérables (as Enjolras).

Circa 1988, he was internationally regarded as the best Enjolras and was honoured by being selected for the complete symphonic recording, along with leading Les Misérables performers from around the world along with fellow Australian actor Philip Quast as Javert.

In 2012, Warlow reprised his role as Daddy Warbucks in Annie at the Lyric Theatre, Star City, for a strictly limited season of 12 weeks.

Warlow made his long-awaited debut on Broadway, New York, in the James Lapine-directed Annie in the role of Daddy Warbucks at the Palace Theatre.

Although he performed for the industry opening night, Warlow was struck down by a bout of influenza that had also claimed many of the other cast and crew, and as a result, he missed the first two and a half weeks of the show's Melbourne season.

After closing in Sydney on 14 September, the production moved to Auckland, New Zealand and following a holiday break, subsequently opened in Perth in February 2009.

Warlow was found to be suffering from Non-Hodgkin's Lymphoma in 1992, during the early publicity for the arena production of Jesus Christ Superstar where he was to appear as Pontius Pilate.

His fourth solo album, Midnight Dreaming, reached the top ten of the Australian Aria Charts.
