Dorothea Helen Puente was a convicted American serial killer. In the 1980s, Puente ran a boarding house in Sacramento, California, and cashed the Social Security checks of her elderly and mentally disabled boarders. Those who complained were killed and buried in her yard. Newspapers dubbed her the "Death House Landlady".

On November 11, 1988, police inquired after the disappearance of tenant Alvaro Montoya, a developmentally disabled schizophrenic whose social worker had reported him missing. After noticing disturbed soil on the property, they uncovered the body of tenant Leona Carpenter, 78. Seven bodies were eventually found, and Puente was charged with a total of nine murders, convicted of three and sentenced to two life sentences. Puente died in prison at Chowchilla on March 27, 2011, from natural causes; she was 82.
