Hillel Day School, named after the Jewish religious leader, sage and scholar Hillel, is an independent Pre-K – 8 Jewish day school in Farmington Hills, Michigan, a city in the Detroit metropolitan area. Founded in 1958, it became the first non-Orthodox Jewish school in Michigan. It provides both secular and Judaic studies instruction for students from preschool through eighth grade.

Hillel initially rented space from various Jewish organizations. In 1970, it settled into its permanent home in Farmington Hills. In 1980s–1990s, portable classrooms were necessary due to overcrowding. Since then, Hillel's campus has undergone significant expansions and renovations. It now features open-space learning areas, a separate pre-school wing, an indoor gym, all-season outdoor athletic facilities, an "innovation hub" with a greenhouse and makerspace, and a café with a kitchen.

In 2005, Hillel controversially closed the teachers' union. In 2008, Hillel ended its affiliation with the Conservative movement and became a non-denominational Jewish day school.
