Luther High School North, formerly known as Luther North College Prep, was a private high school located in the Portage Park neighborhood of Chicago, Illinois.

Its predecessor was Luther Institute, founded in 1909 as a Lutheran High School and located in the Near West Side neighborhood of Chicago.

In 1953 the school moved to a campus in Portage Park, Chicago.

Due to financial difficulties, the Portage Park campus was sold to New Life Community Church in 2010, with the school sharing occupancy.

In February 2017, with an enrollment of only 170 students despite recruiting efforts, the school announced that it would cease operations after the 2016–2017 school year.
