Gabriela Horvátová (25 December 1877 – 29 November 1967) was a Croatian-Czech mezzo-soprano. She is best known for performing the part of the Kostelnička in the Prague premiere of Jenůfa in 1916, (12 years after the world première in Brno, in 1904) and for having become closely involved with the opera's composer Leoš Janáček.
