Maria Barbella (October 24, 1868 – March 24, 1950) was an Italian-born American woman. Erroneously known as Maria Barberi at the time, she was the second woman sentenced to die in the electric chair. She was convicted of killing her lover in 1895, but the ruling was overturned in 1896 and she was freed. Her trial became a cause célèbre in the late 19th century.
