Cumberland County is a county in the U.S. state of Maine. As of the 2020 census, the population was 303,069, making it the most populous county in Maine. Its county seat is Portland. Cumberland County was founded in 1760 from a portion of York County, Province of Massachusetts Bay, and named for William, Duke of Cumberland, a son of King George II. Cumberland County has the deepest and second-largest body of water in the state, Sebago Lake, which supplies tap water to most of the county. The county is the state's economic and industrial center, having the resources of the Port of Portland, the Maine Mall, and having corporate headquarters of major companies such as onsemi, IDEXX Laboratories, Unum, and TD Bank. Cumberland County is part of the Portland–South Portland, ME Metropolitan Statistical Area.

Casco Bay is an inlet of the Gulf of Maine on the coast of Maine in the United States. The National Oceanic and Atmospheric Administration's chart for Casco Bay marks the dividing line between the bay and the Gulf of Maine as running from Bald Head on Cape Small in Phippsburg west-southwest to Dyer Point in Cape Elizabeth. The city of Portland and the Port of Portland are on Casco Bay's western edge.
Sebago Lake (Sih-Bay-Goh) is the deepest and second-largest lake in the U.S. state of Maine. The lake is 316 feet (96 m) deep at its deepest point, with a mean depth of 101 feet (31 m). It is possible that Sebago is the deepest lake wholly contained within the entire New England region, although some sources say that Vermont's Lake Willoughby is slightly deeper. Along with Lake Champlain, Sebago is one of the only lakes in the area that do not consistently freeze solid during the winter months, with total ice cover occurring for only a short period of time every few winters. Sebago covers about 45 square miles (117 km2) in surface area, has a length of 14 miles (23 km) and has a shoreline length of roughly 105 miles (169 km). The surface is around 270 feet (82 m) above sea level, so the deep bottom is below the present sea level. It is in Cumberland County, and bordered by the towns of Casco, Naples, Raymond, Sebago, Standish and Windham. The seasonally occupied town of Frye Island is on an island in the lake. Sebago Lake and the surrounding area is known for its erratic and sudden changes in weather during all seasons, likely due to its proximity to the Atlantic Ocean and to Mt. Washington, a very notorious extreme weather hotspot. The name comes from the Abenaki sobagoo, meaning "it is the sea" or "it resembles the sea".

The Presumpscot River is a 25.8-mile-long (41.5 km) river located in Cumberland County, Maine, United States. It is the main outlet of Sebago Lake.

The Cumberland and Oxford Canal was opened in 1832 to connect the largest lakes of southern Maine with the seaport of Portland, Maine. The canal followed the Presumpscot River from Sebago Lake through the towns of Standish, Windham, Gorham, and Westbrook. The Canal diverged from the river at Westbrook to reach the navigable Fore River estuary and Portland Harbor. The canal required 27 locks to reach Sebago Lake at an elevation of 267 feet (81 m) above sea level. One additional lock was constructed in the Songo River to provide 5 feet (1.5 m) of additional elevation to reach Long Lake from Sebago Lake. Total navigable distance was approximately 38 miles (61 km) from Portland to Harrison at the north end of Long Lake. A proposed extension from Harrison to Bear Pond and Tom Pond in Waterford would have required three more locks on the Bear River, but they were never built.
