Donna Jackson is a fictional character from the BBC medical drama "Holby City", played by actress Jaye Jacobs. She appeared in the programme from its sixth series in 2004, to its thirteenth in 2011, and from its nineteenth in 2017. Donna entered the series as a staff nurse, characterised as a wild-child with a chaotic personal life. During her tenure, she grew to take her work more seriously, becoming a ward sister and accepting more personal responsibilities by adopting her half-niece Mia (Jada Wallace-Mitchell). A tart with a heart character, Donna had many romantic liaisons with her colleagues, including a one-night stand with midwife Mickie Hendrie (Kelly Adams). She ultimately fell in love with agency nurse Kieran Callaghan (Barry Sloane), and departed to be with him after he was injured in Afghanistan as part of the Territorial Army.
