The Wedge (or Delaware Wedge) is a 1.068-square-mile (684-acre; 2.77 km2) tract of land along the borders of Delaware, Maryland and Pennsylvania. Ownership of the land was disputed until 1921; it is now recognized as part of Delaware. The tract was created primarily by the shortcomings of contemporary surveying techniques when the boundaries were defined in the 18th century. It is bounded on the north by an eastern extension of the east–west portion of the Mason–Dixon line, on the west by the north–south portion of the Mason–Dixon line, and on the southeast by the Twelve-Mile Circle around New Castle, Delaware. The crossroads community of Mechanicsville, Delaware, lies within the area today.

The Mason–Dixon line, also called the Mason and Dixon line or Mason's and Dixon's line, is a demarcation line separating four U.S. states, forming part of the borders of Pennsylvania, Maryland, Delaware, and West Virginia (part of Virginia until 1863). It was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon as part of the resolution of a border dispute involving Maryland, Pennsylvania, and Delaware in the colonial United States. The dispute had its origins almost a century earlier in the somewhat confusing proprietary grants by King Charles I to Lord Baltimore (Maryland), and by his son King Charles II to William Penn (Pennsylvania and Delaware). The largest portion of the Mason–Dixon line, along the southern Pennsylvania border, later became informally known as the boundary between the Southern slave states and Northern free states. This usage came to prominence during the debate around the Missouri Compromise of 1820, when drawing boundaries between slave and free territory was an issue, and resurfaced during the American Civil War, with border states also coming into play. The Confederate States of America claimed the Virginia portion of the line as part of its northern border, although it never exercised meaningful control that far north – especially after West Virginia separated from Virginia and joined the Union as a separate state in 1863. It is still used today in the figurative sense of a line that separates the Northeast and South culturally, politically, and socially (see Dixie).

Mechanicsville is an unincorporated community in New Castle County, Delaware, United States.The community is located in "The Wedge", a geometric oddity arising out of ambiguity in the 18th-century border dispute settlement between the Penns and Calverts in the British North American colonies. Until 1921, Mechanicsville was claimed by both Pennsylvania and Delaware. A resolution allocated Mechanicsville and The Wedge to Delaware, which owns it today.

The Delaware–Maryland–Pennsylvania Tri-State Point is the meeting of the northwestern corner of Delaware, the northeastern corner of Maryland, and the southern edge of Pennsylvania. A wooden marker was placed in 1765, by Charles Mason and Jeremiah Dixon, and was replaced with a stone marker in 1849. A trail to the marker was made in 2014–2015.
