The following is a list of notable alumni of The Baltimore City College (also known colloquially as City College, City, BCC, or The Castle). Founded in 1839, it is recognized as the third-oldest continuously public high school in the United States.
The school was established after a long civic campaign for higher public education during the early 19th century by an act of the Baltimore City Council in March 1839 and opened the following October in a rented town / rowhouse. Hundreds of influential civic, political, business, commercial, industrial, and cultural leaders have passed through its doors at eight geographic sites in the 185 years since. Many graduates of City College have served as members of the United States Congress (U.S. senators and representatives), state senators and delegates in the General Assembly of Maryland, the Baltimore City Council, the adjacent surrounding separate Baltimore County Council, and federal, state and local circuit judges. Alumni also include award-winning journalists; authors; and leaders in business, commerce, the military, academics, the sciences, and the arts. This list includes three former governors of Maryland, six mayors of Baltimore and county executives, and recipients of the Nobel Prize, the Pulitzer Prize, and the Wolf Prize. Of the seven Maryland recipients of the Congressional Medal of Honor between World War I and World War II, three were graduates of the Baltimore City College. Numerous bridges, highways, buildings, lunar craters, institutions, monuments, and professorships throughout the region, state and nation have been named for B.C.C. "Collegians".
