Old Hamilton Library

The Old Hamilton Library is a historic library building at 3006 Hamilton Avenue in Baltimore, Maryland. The three-story masonry Beaux Arts building was constructed in 1920 in the Hamilton neighborhood of the city as a branch of the Enoch Pratt Free Library. The building was designed by architect Theodore Wells Pietsch I, who designed a number of other Baltimore landmarks, and funded in part by a grant from steel baron and philanthropist Andrew Carnegie. The building served as a library until 1959, after which it was converted to commercial office use.

The building was listed on the National Register of Historic Places in 2012.
