Büşra Fatma Ün (born 19 May 1994) is a Turkish female Paralympic wheelchair tennis player.
Büşra Ün was born in Izmir. At the age of six-and-half-months, her parents noticed that she has no feeling at her feet. She was diagnosed with neuroblastoma having a malignant tumor in her right abdomen. After one-and-half-year-long chemotherapy and two surgeries, the tumor was removed. However, due to damaged nerves, she became paraplegic.
