The Cumberland County Courthouse is located at 142 Federal Street, Portland ME 04101; phone: 207-871-8380.
The first white settler came to the county no later than 1628. The 1677 purchase of the province by Massachusetts found the area as part of Yorkshire county; the county was organized as Cumberland in 1760.
The county is home to more than two dozen historic districts listed on the National Register of Historic Places.
