Tiếng gọi thanh niên
Tiếng gọi thanh niên, or Thanh niên hành khúc (Saigon: [tʰan niəŋ hân xúk], "March of the Youths"), and originally the March of the Students (Vietnamese: Sinh Viên Hành Khúc, French: La Marche des Étudiants), is a famous song of the Vietnamese musician Lưu Hữu Phước. Its lyrics were revised to become the national anthem of the State of Vietnam from 1949 to 1955 and later the Republic of Vietnam (South Vietnam) from 1955 to 1975, with the name Tiếng gọi công dân ("Call to the Citizens").
