Maria Muldaur (born September 12, 1943) is an American folk and blues singer who was part of the American folk music revival in the early 1960s. She recorded the 1973 hit song “Midnight at the Oasis” and continues to record albums in the folk traditions.

She was the wife of musician Geoff Muldaur and is the mother of singer-songwriter Jenni Muldaur.

Muldaur was born Maria Grazia Rosa Domenica D’Amato in Greenwich Village, New York City, where she attended Hunter College High School.

Muldaur began her career in the early 1960s as Maria D’Amato, performing with John Sebastian, David Grisman, and Stefan Grossman as a member of the Even Dozen Jug Band. She then joined Jim Kweskin & the Jug Band as a featured vocalist and occasional violinist. During this time, she was part of the Greenwich Village scene that included Bob Dylan, and some of her recollections of the period, particularly with respect to Dylan, appear in Martin Scorsese‘s 2005 documentary film No Direction Home.

She married fellow Jug Band member Geoff Muldaur, and after the Kweskin group broke up, the two of them produced two albums. She began her solo career when their marriage ended in 1972, but retained her married name.

Her first solo album, Maria Muldaur, released in 1973, contained her hit single “Midnight at the Oasis“, which reached number 6 on the Billboard Hot 100 in 1974. It also peaked at number 21 in the UK Singles Chart. Later that year, she released her second album, Waitress in a Donut Shop. This included a re-recording of “I’m a Woman“, the Leiber and Stoller number first associated with Peggy Lee and a standout feature from her Jug Band days. The title of this album is taken from a line in another song on the album, “Sweetheart”, by Ken Burgan.
