Judith Veronica Mowatt, OD (born 1952) is a Jamaican reggae artist. As well as being a solo artist, from 1974 she was also a member of the I Threes, the trio of backing vocalists for Bob Marley & The Wailers.

Mowatt was born in Gordon Town, St. Andrew Parish, Jamaica. At the age of 13, she became a member of a dance troupe that toured Jamaica and other islands in the Caribbean. Her initial ambition was to become a registered nurse. Her earliest musical influences were Aretha Franklin, Otis Redding, Curtis Mayfield, Dionne Warwick, Bob Marley, Marcia Griffiths, The Staple Singers and The Soulettes. A coincidental meeting with two teenage girls who were earlier in her dance troupe led to the formation of the Gaylettes, in 1967.

In 1974, Mowatt got her big break by joining Bob Marley's backing vocal trio the "I Threes".

Her Black Woman album (Ashandan, 1979) came out the same year as I Three member Marcia Griffiths's album At Studio One. It is considered by many critics to be the greatest reggae album by a female artist. It was also the first reggae album recorded by a woman acting as her own producer, in collaboration with the renowned Jamaican artist Freddie McGregor, with whom she also had a romantic relationship, resulting in the birth of their daughter Yashemabeth McGregor.

The song "Joseph", from this album, was dedicated to Bob Marley while he was still alive, as she believed that the Jamaican musician was the reincarnation of the biblical figure Joseph from the Old Testament.

She became the first female singer nominated for a Grammy Award in the category of reggae music when her Working Wonders album was nominated in 1985.

Formerly a member of the Rastafari movement, in the late 1990s she converted to Christianity and now sings Gospel music.

In 1999 the Jamaican government made her an Officer of the Order of Distinction for "services to music".
