Interstate 84 (I-84) is an Interstate Highway in the Northeastern United States that extends from Dunmore, Pennsylvania, (near Scranton) at an interchange with I-81 east to Sturbridge, Massachusetts, at an interchange with the Massachusetts Turnpike (I-90). Among the major cities that the road passes through is Hartford, Connecticut, and the road provides a major portion of the primary route between New York City and Boston. Another highway named I-84 is located in the Northwestern United States.

After , I-84 interchanges with I-380, with I-380 going southeast through the Poconos and I-84 continuing almost due east into Wayne and Pike counties. Pennsylvania began replacing sequential exit numbers with mile-based numbers in 2001. This section of Pennsylvania is very lightly populated, and there are no major settlements on or near I-84, although it offers access to popular outdoor recreation areas such as Lake Wallenpaupack and Promised Land State Park. Its right-of-way is very wide, with a large median strip between the two roadways as it passes through densely wooded country, except for the swampy areas in southern Wayne County. The only development along Pennsylvania's section of I-84 is where US Route 6 (US 6) and US 209 start to parallel closely and form a commercial strip just south of Matamoras, just west of the Delaware River. I-84 reaches its highest elevation in Pennsylvania and in the east just west of exit 8 at . New York I-84 enters New York by crossing both the Delaware and Neversink rivers on a long bridge south of Port Jervis, the first large settlement near the highway. South of the road, at the confluence of the Delaware and Neversink rivers, is the Tri-States Monument, where New Jersey, New York, and Pennsylvania converge. The first mile () of the road in New York runs along the New Jersey state line, then curves to the north to climb the Shawangunk Ridge and cross Orange County, where it intersects New York State Route 17 (NY 17; future I-86) and later the New York State Thruway (I-87). I-84 includes the Newburgh–Beacon Bridge across the Hudson River at Newburgh. East of the bridge and the city of Beacon, I-84 continues to head east across Dutchess County, beginning to turn
