Tzeni Karezi (Greek: Τζένη Καρέζη, January 12, 1932 - July 26, 1992) was a Greek film and theatre actress. She was considered one of the most popular and successful actresses of the cinema of Greece.
Tzeni (or Jenny) Karezi was born Evgenia Karpouzi, in Athens, to highly educated parents; her father was a mathematician and her mother a high school teacher. She studied under the direction of nuns in a private French school in Thessaloniki and as a result she spoke French fluently. When she was a teenager, her father left the family and she continued to live with her mother. She did not see her father until he died in a car accident, in 1971. Tzeni also had a sister named Euterpe, named after the nine muses, that she found after she was adopted by her mother.
In 1951 she was accepted at the Greek National Theater (Eθνικό Θέατρο), where she studied in the Drama School. The playwright Angelos Terzakis and the director Dimitris Rontiris were among her teachers.
