James Lance Bass (; born May 4, 1979) is an American pop singer, dancer, actor, film and television producer, and author. He grew up in Mississippi and rose to fame as the bass singer for the American pop boy band NSYNC. NSYNC's success led Bass to work in film and television. He starred in the 2001 film On the Line, which his company, Bacon & Eggs, also produced.

Bass guest-starred on the WB drama series 7th Heaven, playing Rick Palmer, a love interest for Beverley Mitchell's character, Lucy. The following year, while NSYNC was in the midst of recording Celebrity, Bass received his first starring role in the 2001 motion picture On The Line. Bass played Kevin, a man who falls in love with a woman on a Chicago train and begins a search to find her again. The film was produced by Bass's production company, A Happy Place (later renamed Bacon & Eggs), and featured appearances by Jerry Stiller, Al Green, Bon Jovi guitarist Richie Sambora, former WWE wrestler Chyna, and Bass's bandmates Timberlake, Kirkpatrick and Fatone, the latter in a major role. The film also featured a soundtrack which included previously unreleased songs by NSYNC and Britney Spears. Bass collaborated with Joey Fatone, Mandy Moore, Christian Burns and True Vibe (as the "On The Line Allstars") for the film's theme song, "On The Line". Despite heavy marketing towards NSYNC teen fans, the film was a commercial failure, grossing only $4.2 million US domestically despite its $10 million US budget. The film, along with Bass's acting, was also poorly received by critics. Bass later said that he felt the film's success was greatly hindered by its release date, which came one week after the World Trade Center attacks of September 11, 2001. In his 2007 autobiography, Bass wrote, "That was it - our film was finished... once the country went to war, there was no way our film was going to be on anyone's top-priority list." After On The Line, Bass appeared in Zoolander and Wes Craven's Cursed as himself, and played a wedding singer in I Now Pronounce You Chuck and Larry. Bass has also lent his voice to several animated television programs, such as Robot Chicken and Disney's Kim Possible, Handy Manny and Higglytown Heroes. In the video game realm, Bass voiced the Final Fantasy VII character Sephiroth in Kingdom Hearts. On August 14, 2007, Bass began a six-month stint playing Corny Collins in the Broadway musical Hairspray, coinciding with the play's five-year stage anniversary. He ended his run in Hairspray on January 6, 2008. Bass made an appearance in the 2008 film Tropic Thunder. As a guest star in the 2013 Gravity Falls episode "Boyz Crazy", Bass plays in the boy band, Sev'ral Timez (which is a parody of NSYNC). In 2014, Bass guest starred on an episode of the Comedy Central series, Review, in which he visited space along with the show's lead character. In 2015, Bass joined season two of The Meredith Vieira Show as a full-time contributing panelist. Bass and his mother competed with other duos in the FOX reality cooking series My Kitchen Rules.
