Francis Howell North High School (FHN) is a four-year public secondary school located in St. Peters, Missouri, with a St. Charles postal address.

After Francis Howell High School alone could no longer support the increasing population of its part of St. Charles County in 1983, Henderson Junior High School was built on Hackmann Road on the border of the cities of St. Charles and St. Peters.

Henderson was eventually expanded and the name was changed to Francis Howell North High School and began taking high school students in 1986.

The school is named after the early settler and militia leader Col. Francis Howell, who moved to St. Charles in 1797.

The high school's newspaper, The North Star, has earned multiple national awards.
