Morrill Hall is the oldest continuously-used academic building on the campus of the University of Maryland, College Park.

Built in 1898 in the Second Empire architectural style for $24,000,[2] it was the sole academic building left untouched by The Great Fire of 1912 which devastated almost all of campus.

The three-story building currently houses a number of offices in the College of Behavioral and Social Sciences, including the Center for American Politics and Citizenship.

Morrill Hall is currently being considered for addition to the Prince George's County historic landmark list.
