The Hillsborough County Registry of Deeds is located at 19 Temple Street in Nashua, one of the county seats of Hillsborough County, New Hampshire. The two-story brick building was built in 1901 as a courthouse and county office building to a design by Boston architect Daniel H. Woodbury, and is a good example of Classical Revival architecture. The building was listed on the National Register of Historic Places in 1985. The current courthouse is a modern building at 30 Spring Street.
