Metro Academic and Classical High School is a magnet public high school in St. Louis, Missouri, United States, that is part of the St. Louis Public Schools school district.

As of the 2018–19 school year, the school had an enrollment of 377 students and 24 classroom teachers (on an FTE basis), for a student–teacher ratio of 15.7:1. There were 374 students (99.2% of enrollment) eligible for free lunch and none eligible for reduced-cost lunch.

Metro is notable for being one of two International Baccalaureate World Schools in Missouri. Their IB Diploma Programme is coordinated by Sharleta Williams.

Metro opened in 1972 in a five-room building at 2135 Chouteau Avenue as an alternative public high school. It became one of the first magnet schools in the St. Louis Public Schools district in 1981. In the early 1980s, the school moved to the Temple Israel building at 5017 Washington Place and in 1996, it moved to its current location in a purpose-built school building.

In 1997, the school's founder and principal, Betty M. Wheeler, retired (and, in 2022, the former Kennard Junior Classical Academy was re-named the Betty Wheeler Classical Junior Academy, in her honor). Her replacement, Pamela Randall, served until 2003, when she entered district administration and later served as acting superintendent of the St. Louis Public Schools. Randall's replacement, Wilfred Doug Moore, was principal from 2003 to 2017, followed by Steven Lawler. In 2022, Lawler retired as the principal of Metro, and Dr. Tina Wallace-Hamilton became Metro's principal at the start of the 2022-23 school year.

All Metro students are required to perform 200 hours of community service prior to graduation.
