Commercial Street is a downtown street in the Old Port of Portland, Maine, United States. It is part of U.S. Route 1A.

Built upon old piers in the 1850s, fill was pushed into Casco Bay to accommodate the growing railroad and warehousing needs of the port's working waterfront.

Five years before the Great Chicago Fire, this was the greatest fire yet seen in an American city. It started in a boat house on Commercial Street, likely caused by a firecracker or a cigar ash. The fire spread to a lumber yard and on to a sugar house, then spread across the city, eventually burning out on Munjoy Hill in the city's east end. Two people died in the fire and 10,000 people were made homeless. 1,800 buildings were burned to the ground. This included the federal Exchange Building by which was replaced with the custom house.

The Burning of Falmouth (October 18, 1775) was an attack by a fleet of Royal Navy vessels on the town of Falmouth, Massachusetts (site of the modern city of Portland, Maine, and not to be confused with the modern towns of Falmouth, Massachusetts or Falmouth, Maine). The fleet was commanded by Captain Henry Mowat. The attack began with a naval bombardment which included incendiary shot, followed by a landing party meant to complete the town's destruction. The attack was the only major event in what was supposed to be a campaign of retaliation against ports that supported Patriot activities in the early stages of the American Revolutionary War. Among the colonies, news of the attack led to rejection of British authority and the establishment of independent governments. It also led the Second Continental Congress to contest British Naval dominance by forming a Continental Navy. Both Mowat and his superior, Vice-Admiral Samuel Graves, who had ordered Mowat's expedition, suffered professionally as a consequence of the event.
