The Delmarva Peninsula is a long stretch of land on the East Coast of the United States.

It is a unique geographic feature that belongs to three different states. Most of the peninsula is occupied by the state of Delaware. Parts of the Eastern Shore of Maryland and the Eastern Shore of Virginia also sit on the peninsula. The name "Delmarva" is a clipped compound. It combines the names of Delaware, Maryland, and Virginia. This name was modeled after Delmar, a border town founded in 1859. While the term appeared in newspapers as early as 1877, it did not see general use until the 1920s.

The peninsula is defined by the water that surrounds it. To the east lies the Atlantic Ocean and the Delaware Bay. The Delaware River also borders the eastern side. To the west, the Chesapeake Bay sits against the land. Pocomoke Sound borders the southwest.

The map from 1778 shows the region as the peninsula between the Delaware and Chesapeake bays. The land itself is part of the Atlantic Coastal Plain. This means the area is very flat and sandy. There are almost no hills here. In fact, the highest points in the region are only slightly above sea level.

Human history on the peninsula stretches back thousands of years. Studies suggest Native Americans inhabited the area from about 10,000 BC to 8,000 BC. Some research into the pre-Clovis period suggests even earlier human presence. For example, archaeological sites like Miles Point and Oyster Cove document people in the Middle Atlantic region. In 1970, a stone tool was found off the coast of Virginia. This area would have been dry land during the Pleistocene Epoch. Indigenous groups like the Assateague lived on the ocean side. They lived in villages made of thatch houses and cultivated gardens. They moved their settlements when the farmland became less productive.

European colonization brought significant changes to the peninsula. In 1566, a Spanish expedition led by Pedro Menéndez de Avilés reached the area. They hoped to find the fabled Northwest Passage. However, a storm prevented them from establishing a colony. In 1631, the Dutch West India Company founded a colony called Zwaanendael. This settlement lasted only one year before a dispute with local Indians led to its destruction. Later, New Sweden was established in 1638. Eventually, the British took control of the region. The state of Delaware was formed in 1776 when three counties declared independence from Pennsylvania.

Political boundaries on the peninsula were often the subject of long disputes. A major conflict known as the Penn-Calvert Boundary Dispute lasted for 80 years. This disagreement involved the borders between Maryland and Delaware. The dispute was finally settled by the Chancery Court in 1735. Another legal case, Penn v. Lord Baltimore, helped clarify land rights. It decided that Maryland's claim to Delaware was void because the Dutch had already colonized Zwaanendael. These legal battles helped shape the exact lines we see on maps today. The current border includes the Transpeninsular Line and part of the Mason-Dixon line.

Today, the peninsula is a place of both rural life and growing populations. As of the 2020 census, the twelve counties on the peninsula had 818,014 people. The largest city in Delaware is Dover. Salisbury, Maryland, is another major commercial center near the middle of the peninsula. The climate is classified as humid subtropical. This means the weather is often warm and moist. Many people work in agriculture or commercial fishing. Tourism is also a very important part of the local economy.

Visitors often travel to the Delaware Beaches or Ocean City, Maryland.

Traveling across the peninsula requires using various bridges and waterways. The Chesapeake and Delaware Canal cuts through the northern isthmus. This canal separates the land at a very narrow point. Several bridges cross this canal to allow travel. The Chesapeake Bay Bridge and the Bridge-Tunnel connect the peninsula to mainland Maryland and Virginia. Travelers can also reach Lewes, Delaware, by using the Cape May-Lewes Ferry from New Jersey.
