Largest Public Schools in Baltimore, MD
The largest public schools located in Baltimore, Maryland, ranked by enrollment in the 2023–24 NCES Common Core of Data, with lunch-eligibility figures for each campus.
Public schools physically located in Baltimore enrolled 151,639 students in the 2023–24 school year across 271 campuses with reported enrollment. City pages answer a different question from district pages: a district is a governing agency that can span many cities, while this page groups individual campuses by the city in their CCD location address. The distinction matters in metros like Baltimore, where one district may run most campuses but charter and neighboring-district schools also sit inside city limits. Every figure here is a campus figure from the school-level CCD files, labeled 2023–24.

The largest campus, Dundalk High, enrolled 2,159 students — 1.4% of all students in schools located in the city. Large comprehensive high schools dominate the top of most city rankings because elementary schools are deliberately kept small and neighborhood-based, while high schools consolidate whole districts into a few campuses. Where a very large campus is a virtual or alternative school, its CCD school type says so in the source file, and readers should weigh that before comparing it with a traditional campus.
Reading the lunch-eligibility column
Across the 15 largest Baltimore campuses that reported lunch counts, 59.0% of students were eligible for free or reduced-price lunch in 2023–24.
Eligibility is a family-income measure collected through the National School Lunch Program and reported to NCES by each school. Campuses marked n/r did not report a usable count — in some cases because the school serves all meals free under the Community Eligibility Provision and reports through a different route. The column is therefore best read campus by campus, and the aggregate above is computed only over reporting campuses, which the text states openly rather than burying in a footnote.
How city totals relate to district totals
If you add the campuses here, the sum will not match any single district’s enrollment, and it is not supposed to: district totals count every student a district serves wherever the campus sits, while this page counts every student in campuses located in Baltimore whichever district runs them. For agency-level figures — staffing, spending and diplomas — use the district pages in the district index or the Maryland state pages for statewide totals. Both views come from the same 2023–24 CCD files; they simply group the same schools two different ways.
