Dora Pejačević (September 10, 1885 – March 5, 1923) was a Croatian composer, a member of Pejačević noble family. Dora Pejačević (in old documents also Pejacsevich) was born in Budapest, a daughter of Croatian ban Teodor Pejačević and Hungarian Countess Lilla Vay de Vaya, herself a fine pianist. Her mother gave her first piano lessons. Paternally, she descended from the old Croatian noble Pejačević family, one of the most distinguished noble families in Slavonia, eastern region of Croatia.
