Hanna Helena Chrzanowska (7 October 1902 – 29 April 1973) was a Polish Roman Catholic who served as a nurse and was also a professed member of the Benedictine oblates. Chrzanowska worked in her profession 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 with cancer.
