Anton Fig (born 8 August 1952) is a South African session drummer perhaps best known as the drummer and second-in-command for Paul Shaffer and the World's Most Dangerous Band. David Letterman, for whom the band served as house band on his late-night talk shows, often called Fig "Anton Zip" or "Buddy Rich Jr." Fig is also known for his work with Kiss, Ace Frehley, and Joe Bonamassa.

Fig was born in Cape Town, South Africa. He began playing drums at age four. After performing in numerous bands in Cape Town, becoming locally respected with bands like Hammak, he moved to Boston to further pursue his musical interests. His formal education included studies at the New England Conservatory of Music, where he studied jazz and classical music and graduated with honors in 1975. In 1976, he moved to New York City, where he began to work as a freelance musician.

Fig was a member of the band Spider during both its album releases in 1980 and 1981 as well as on its 1982 album under the name Shanghai, together with producer Beau Hill and songwriter Holly Knight.

Fig was the drummer on Ace Frehley's 1978 eponymous solo album and subsequently became a member of the then ex-Kiss lead guitarist's solo project Frehley's Comet from 1984 to 1987. Fig also played drums on all but one song on Kiss's 1979 album Dynasty and every song on its 1980 album Unmasked; the use of Fig to replace usual drummer Peter Criss (producers thought Criss, who had a drug problem, had seen a deterioration of his skills) upset Criss, to the point where, after appearing in promotional videos and tours through Unmasked, he left the band.

Other artists Fig has worked with include Bob Dylan, Mr Scary, Warren Zevon, B. B. King, Booker T and The MGs, Peter Frampton, Joan Armatrading, Cyndi Lauper, Link Wray, John Waite, Robert Gordon, Eric Johnson, Beth Hart, Oz Noy, and Kix.

Fig became the drummer for the Paul Shaffer-led house band of David Letterman's late night television shows in 1986, when he debuted with "The World's Most Dangerous Band" on NBC's Late Night with David Letterman. When Letterman's show moved to CBS in 1993 and became Late Show with David Letterman, the band (and Fig) moved as well, adding a horn section and becoming known as the "CBS Orchestra".

During this tenure, Fig and the rest of the band played with artists including Miles Davis, James Brown, Bruce Springsteen, Steve Winwood, Bonnie Raitt, and Tony Bennett. Fig also played parts in several of the show's comic sketches, including the recurring gag "Anton Fig's Guess The Expiration Date", in which Fig would be blindfolded and fed a perishable food product and attempt to guess the expiration date on the item solely by tasting it. The CBS Orchestra also backed up artists in other venues, such as Stevie Wonder, Faith Hill, Little Richard, and, at the closing ceremonies of the 1996 Olympic Games in Atlanta, B. B. King. It also backed Al Green, Gloria Estefan, 'N Sync, and Eric Clapton for VH1's Save the Music concert at the White House.

The World's Most Dangerous Band is also the house band for the Rock and Roll Hall of Fame, and the backup band for The Concert for New York City, where it performed with David Bowie, Mick Jagger and Keith Richards, Eric Clapton and Buddy Guy, Macy Gray, and James Taylor.
