Justin Randall Timberlake (born January 31, 1981) is an American singer, songwriter, record producer, and actor. Dubbed the "Prince of Pop", he is regarded as one of the most influential entertainers of his generation. According to Billboard, Timberlake is the best performing solo act on Pop Airplay, and remains one of the best-selling recording artists of all time with sales of over 117 million records worldwide. He has won numerous awards and accolades, including ten Grammy Awards, four Primetime Emmy Awards, three Brit Awards, nine Billboard Music Awards, the Contemporary Icon Award by the Songwriters Hall of Fame, and MTV's Michael Jackson Video Vanguard Award.

Born and raised in Memphis, Tennessee, Timberlake appeared on musical television shows as a child, competing on Star Search; in the early to mid-1990s, he was a main cast member of the Disney Channel's Mickey Mouse Club, performing cover songs and choreography. While on the show, Timberlake worked with future bandmate JC Chasez, as well as future pop cultural figures including Britney Spears, Christina Aguilera, Keri Russell and Ryan Gosling. Timberlake and Chasez later rose to prominence in late 1997 as the lead vocalists for the boyband NSYNC. The group released four commercially successful studio albums, becoming one of the best-selling boy bands of all time with sales of over 70 million units worldwide.

Timberlake's debut solo album, Justified (2002), yielded his first solo hit singles, "Cry Me a River" and "Rock Your Body". His second album, FutureSex/LoveSounds (2006), reached further success as it debuted atop the US Billboard 200 and spawned three consecutive Billboard Hot 100 number-one singles: "SexyBack" (featuring Timbaland), "My Love" (featuring T.I.) and "What Goes Around... Comes Around". Established as a solo artist worldwide, his first two albums both exceeded sales of 10 million copies and received triple platinum certification by the RIAA. Meanwhile, Timberlake collaborated with other artists on a string of successful singles, including The Lonely Island's viral hit "Dick in a Box" in 2006, his fourth US number-one single with Timbaland's "Give It to Me" in 2007, as well as Madonna's "4 Minutes", 50 Cent's "Ayo Technology" and T.I.'s "Dead and Gone" in the following years.

From 2008 through 2012, Timberlake paused his musical career to focus on acting, starring in the films The Love Guru (2008), The Social Network (2010), Bad Teacher (2011), Friends with Benefits (2011), and In Time (2011). He returned to recording in 2013 with his third and fourth albums, The 20/20 Experience and The 20/20 Experience – 2 of 2; both of which peaked at number one on the Billboard 200 and spawned the Hot 100 top-ten singles "Suit & Tie" (featuring Jay-Z), "Mirrors", and "Not a Bad Thing". The 20/20 Experience became the best-selling album of that year. Timberlake voiced the character Branch in DreamWorks’ Trolls franchise; the soundtrack for the first film included his fifth U.S. number-one single, "Can't Stop the Feeling!", which earned him an Academy Award nomination. He had also previously voiced Artie in Shrek the Third. His fifth studio album, Man of the Woods (2018) became his fourth US number-one album and was supported by two top-ten singles, "Filthy" and "Say Something" (featuring Chris Stapleton); it was named the sixth best-selling album of that year. His sixth studio album, Everything I Thought It Was (2024), became his sixth consecutive top five album in the U.S. The album was preceded by two singles, the top-twenty single, "Selfish" and "No Angels", as well as the promotional single "Drown".
