Mihaela Valentina Runceanu (4 May 1955 – 1 November 1989) was a Romanian pop singer and vocal techniques teacher.
Many of her songs were hits, and she released two albums, Mihaela Runceanu (1987) and Pentru voi, muguri noi (1989), the latter only one day before she was murdered in her home in Bucharest.
In Bucharest on 1 November 1989, a personal friend of hers, Daniel Ștefănescu, visited her and insisted that they watch a videotape he had obtained (at the time, video material circulation was severely restricted by the communist government).
He then stole jewelry, electronics, and some other items that were difficult to obtain in Romania at the time, such as meat, imported cigarettes, and gasoline.
After the Romanian Revolution of 1989, more information about the circumstances of her death was revealed, and details of the murderer's trial appeared in a local Buzău newspaper in 1990.
Later, Nicolae Peneş wrote two books about Mihaela Runceanu, containing her biography as well as details of Ştefănescu's trial published in 1990.
