Mashgiach ruchani (Hebrew משגיח רוחני) or mashgiach for short, means a spiritual supervisor or guide. It is a title which usually refers to a rabbi who has an official position within a yeshiva and is responsible for the non-academic areas of yeshiva students' lives. The position of mashgiach ruchani arose with the establishment of the modern "Lithuanian-style" mussar yeshivas. Some yeshivas may refer to a mashgiach ruchani as a menahel ruchani (the word "menahel" means "principal, as in the principal of a school, or "supervisor.")
