Hanna Helena Chrzanowska, sometimes anglicized as Hannah Helen Chrzanowska, was a Polish Roman Catholic who served as a nurse and was also a Benedictine oblate. Chrzanowska worked as a nurse during World War II when the Nazi regime targeted Poles, but she tended to the wounded and the ailing throughout the conflict and sought to minimize suffering in her own parish. Chrzanowska was awarded two prestigious Polish awards for her good works and died in 1973 after an almost decade-long bout of cancer.
