Judith Glory Hill is an American singer-songwriter from Los Angeles, California. She has provided backing vocals for such artists as Michael Jackson and Josh Groban. In 2009, Hill was chosen as Jackson's duet partner for the song "I Just Can't Stop Loving You" during his This Is It concerts. After Jackson's death in 2009, she, along with the rest of the This Is It cast members, performed at Jackson's memorial service and attracted global attention when she sang the lead on the song "Heal the World". Hill's rise to fame is recounted in 20 Feet from Stardom, a documentary film that tells the untold story of the backup singers behind some of the "greatest musical legends of the 21st century". She is also a featured artist on the film's soundtrack. She won the Grammy Award for Best Music Film for her performance in this film.

A number of Hill's original ballads, including "Desperation" were featured in the 2012 Spike Lee film Red Hook Summer. In March 2013, Hill became a contestant during the fourth season of The Voice. Hill opened for Josh Groban during the third leg of his All That Echoes World Tour (North America) in Fall 2013. She also performed two duets with him in his set for "The Prayer" and "Remember When It Rained", the latter of which was released as a single. She also toured with John Legend on the UK leg of his #AllOfMe tour in the Fall of 2014.

Her debut album Back in Time, recorded at Paisley Park with Prince as co-producer, was officially released as a free download on Judith Hill's WeTransfer account on March 23 and made available until March 25, 2015, via a Livenation email with a note from Prince.
