Joshua Winslow "Josh" Groban (born February 27, 1981) is an American singer-songwriter. He has concentrated his career so far mostly in concert singing and recordings, although he has stated that he wishes to pursue music theatre in the future. As of July 2009, he has sold 19,147,000 albums in the United States alone. Groban received a Grammy for his song Believe and was nominated for an Academy Award in 2005.

Groban was born in Los Angeles to a schoolteacher mother and a businessman father. His father is of Russian Jewish descent and his Norwegian American mother's grandparents were from the eastern Norwegian district of Toten. Groban was raised an Episcopalian. Chris, his younger brother by four years, shares a birthday with him. He stands 5' 9.75" (177 cm).

Groban debuted as a singer in seventh grade, but soon put it on hold for a few years. "I enjoyed the arts aspects, but my grades were slipping. I didn't feel that I was getting enough creative input. So I went to Bridges Academy to get my grades up to straight A's." While at the Academy, Groban took normal classes from 9 AM to 1 PM, and then afterwards attended theatre classes. In 1997 and 1998, Groban attended the Interlochen Center for the Arts in Michigan, majoring in music theatre, which is also when he began taking vocal lessons outside of school.
