The Israel Putnam School is an historic school on School and Oak Streets in Putnam, Connecticut. The school, named in honor of Israel Putnam, is a two-story Classical Revival brick building with limestone trim built in 1902. It has a large central block with smaller flanking wings, and a matching two-story addition extending to the rear, built in 1922. The school was built to address the inadequate conditions of the previous school that served much of the city's industrial population, and was the city's first school building to include an auditorium.The building was listed on the National Register of Historic Places in 1984. It has been converted to residences.
