Myrtis is the name given by archaeologists to an 11-year-old girl from ancient Athens, whose remains were discovered in 1994–95 in a mass grave during work to build the metro station at Kerameikos, Greece. The name was chosen from common ancient Greek names. The analysis showed that Myrtis and two other bodies in the mass grave had died of typhoid fever during the Plague of Athens in 430 BCE.
The United Nations Regional Information Centre made Myrtis a friend of the Millennium Development Goals and used her in the UN campaign "We Can End Poverty".
