Mazowsze, officially known as Państwowy Zespół Ludowy Pieśni i Tańca "Mazowsze" im. Tadeusza Sygietyńskiego, is a Polish folk song and dance ensemble established by decree of the Ministry of Culture and Art on November 8, 1948. Founded by Tadeusz Sygietyński and Mira Zimińska-Sygietyńska to preserve and promote Polish regional folk traditions, Mazowsze staged its premiere at the Polish Theatre in Warsaw on November 6, 1950. The group began touring internationally in 1951, initially visiting the Soviet Union, followed by performances in Paris in 1954 and the United States in 1960. Notable albums include Lowiczanka (Lowicz Girl) (1976) and Boże Coś Polskę (1982). After Sygietyński's death in 1955, Mira Zimińska-Sygietyńska took over leadership and continued expanding the ensemble's repertoire. Mazowsze appeared in several films, including Przygoda na Mariensztacie (1954) and Pan Tadeusz (1999). Over the course of its career, the ensemble has performed in 51 countries across six continents and has become known as an "Ambassador for Polish Culture." In 2025, Mazowsze released the album Dwoje ludzieńków, featuring interpretations of Polish poetry, including works by Maria Konopnicka.
