Marta Kubišová (born 1 November 1942) is a Czech singer. By the time of the Prague Spring of 1968, with her song "Modlitba pro Martu" ("A prayer for Marta"), she was one of the most popular female singers in Czechoslovakia.

In 1967 she won Zlatý slavík award (English: Golden Nightingale). Her song "Prayer for Marta" became a symbol of national resistance against the occupation of Warsaw Pact troops in 1968. During the Prague Spring, she recorded over 200 SP records and one LP, Songy a Balady (Songs and Ballads, released in 1969), which was immediately banned from stores. In 1970, the government falsely accused her of making pornographic photographs leading to a ban from performing in the country until 1989. In 1971, she arranged Angelo Michajlov's score for Dívka na Koštěti (The Girl on a Broomstick). She was a signatory of the Charter 77 proclamation. Her first LPs after the Velvet Revolution in 1989 were a re-issue of Songy a Balady and a compilation of old songs, titled Lampa.
