Tekla Bądarzewska-Baranowska (1829/1834 – 29 September 1861) was a Polish composer. Her grave in the Powązki Cemetery features a young woman with a roll of sheet music titled La prière d'une vierge. One of her daughters, Bronisława, was enrolled at the Warsaw Institute of Music in 1875. A crater on Venus is named after her.
Bądarzewska wrote about 35 small compositions for piano; by far her most famous composition is the piece Modlitwa dziewicy, Op. 4 ("A Maiden's Prayer", French: La prière d'une vierge), which was published in 1856 in Warsaw, and then as a supplement to the Revue et gazette musicale de Paris in 1859.
