Daniel Leo Sultan is an Australian alternative rock singer-songwriter and guitarist, actor and author. At the ARIA Music Awards of 2010 he won Best Male Artist and Best Blues & Roots Album for his second album, Get Out While You Can (November 2009). At the 2014 ceremony he won Best Rock Album for Blackbird (April 2014), which had reached number four on the ARIA Albums Chart. In 2017, Sultan's record Killer was nominated for three ARIA awards: Best Male Artist, Best Rock Album, and Best Independent Release. Sultan's debut children's music album Nali & Friends was named Best Children's Album at the ARIA Music Awards of 2019.

Sultan is a Arrente/Gurindji man.

Sultan started playing guitar at four and wrote his first song at ten. His mother's friend gave him an "old, clapped-out electric guitar" and, when living in Fitzroy, he began singing at local pubs. In 2000 he met Scott Wilson, a guitarist, at a Williamstown pub's karaoke night and the pair began writing tracks together. Wilson later recalled "What struck me at first was that he could play piano and guitar and he was a great foil for what I was doing... After a while playing together he said, 'Can I sing this one?' I said, 'Do you know the words?'... [he had a] mighty voice. A lot of people can play guitar... Not many can sing like that."

Sultan released his debut solo album, Homemade Biscuits on 13 March 2006, with most tracks written by Scott Wilson or co-written by Sultan and Scott Wilson. It was produced by Scott Wilson at Flowerpress Studios, Newport, and True Form Services, Spotswood. Other performers on the album were Lazare Agnekis, Neil Gray, Elijah Maiyah, Lochile McKlean and Ben Wicks. He received the financial assistance of John Butler's Seed program.

At the 2007 Deadly Awards, Sultan won the Single Release of the Year for "Your Love Is Like a Song", which was co-written with Wilson. He performed his self-written track, "Roslyn", at the National Sorry Day concert in May 2007, which describes his mother, a member of the stolen generation, removed from her family when she was six or seven.

Sultan and Wilson were invited by Paul Kelly to record a cover version of "This Land Is Mine", originally by singer-songwriter Kev Carmody, for a various artists tribute album of Carmody's work, Cannot Buy My Soul which was released in February 2007. They also performed at two concerts of the same name: the Sydney Festival in January 2008 and Queensland Music Festival in August 2009. In January 2008 Sultan's backing band consisted of Eugene Ball on trumpet, Ben Gillespie on trombone, Joshua Jones on bass guitar, Peter Marin on drums, Ash Naylor on guitar and Gina Woods on keyboards. Sultan and his band have performed at Australian music festivals.

In November 2009, Sultan released his second studio album, Get Out While You Can, which peaked in the ARIA Albums Chart top 100 in late May 2010 – six months after it was issued. It reached No. 1 on the independent Australian charts and was a Triple J feature album. Sultan describes his music as "country soul rock'n'roll". At the ARIA Music Awards of 2010 he won Best Male Artist and Best Blues & Roots Album for Get Out While You Can. In October that year, he also won Best Independent Artist and Best Independent Blues & Roots Album at the Australian Independent Record Awards (AIR Awards).

In February 2014 Sultan supported Bruce Springsteen's Melbourne and Hunter Valley gigs on his Australian tour.
