Easton is the easternmost city in the Lehigh Valley, a region of 731 square miles (1,893 km2) that is home to more than 800,000 people. Together with Allentown and Bethlehem, the Valley embraces the Allentown-Bethlehem-Easton metropolitan area, including Lehigh, Northampton, and Carbon counties within Pennsylvania, and Warren County in the adjacent state of New Jersey. Easton is the smallest of the three Lehigh Valley cities, with approximately one-fourth of the population of the largest Lehigh Valley city, Allentown.

The city is split up into four sections: Historic Downtown, which lies directly to the north of the Lehigh River, to the west of the Delaware River, continuing west to Sixth Street; The West Ward, which lies between Sixth and Fifteenth Streets; The South Side, which lies south of the Lehigh River; and College Hill, a neighborhood on the hills to the north of downtown, which is the home of Lafayette College, a liberal arts and engineering institution. The boroughs of Wilson, West Easton, and Glendon are also directly adjacent to the city; the first and largest of which, Wilson, partially aligns in the same North-South Grid as the city of Easton.
The greater Easton area consists of the city, three townships (Forks, Palmer, and Williams), and three boroughs (Glendon, West Easton, and Wilson).
