Mark Anthony "Baz" Luhrmann (born 17 September 1962) is an Australian filmmaker and actor with projects spanning film, television, opera, theatre, music and recording industries. He is regarded by some as a contemporary example of an auteur for his style and deep involvement in the writing, directing, design, and musical components of all his work. He is the most commercially successful Australian director, with four of his films in the top ten highest worldwide grossing Australian films of all time.

On the screen he is best known for his "Red Curtain Trilogy", consisting of his romantic comedy film Strictly Ballroom (1992), and the romantic tragedies William Shakespeare's Romeo + Juliet (1996) and Moulin Rouge! (2001). Following the trilogy, projects included Australia (2008), The Great Gatsby (2013), Elvis (2022), and his television period drama The Get Down (2016) for Netflix. Additional projects include stage productions of Giacomo Puccini's La bohème for both the Australian Opera and Broadway and Strictly Ballroom the Musical (2014).

Luhrmann is equally known for his Grammy-nominated soundtracks for Moulin Rouge! and The Great Gatsby, as well as his record label House of Iona, a co-venture with RCA Records. Serving as producer on all of his musical soundtracks, he also holds writing credits on many of the individual tracks. His album Something for Everybody features music from many of his films and also includes his hit "Everybody's Free (To Wear Sunscreen)".
