Jelka Ređep (née Petrović) (Serbian: Јелка Ређеп; 27 April 1936 – 18 December 2014) was a Serbian literary historian and professor known for her influential research on medieval Serbian literature and oral tradition. A longtime faculty member at the University of Novi Sad, she specialised in the Kosovo legend and the interplay between written and folk narratives.
