Cairo is a city in Alexander County, Illinois, United States, located at the confluence of the Ohio and Mississippi Rivers near the southernmost point of the state. It serves as the county seat of Alexander County and is the only city in Illinois situated on both the Ohio and Mississippi rivers.
Geography
Cairo lies at approximately 37°04′N 89°11′W. The city occupies an area of about 4.7 square miles (12.2 km²), of which roughly 2.5 % is water. Its strategic position at the meeting point of two major waterways historically made it a key transportation and trade hub.
History
Founded in 1818 and incorporated in 1865, Cairo was named after the Egyptian city of the same name, reflecting the founders’ fascination with the ancient world's grandeur. In the 19th century, the city prospered as a river port and a railroad junction, serving as a critical supply point during the American Civil War. Post‑war economic decline, coupled with repeated flooding and demographic changes, led to a steady population decrease throughout the 20th and early 21st centuries.
Demographics
According to the 2020 U.S. Census, Cairo had a population of 1,733 residents. The racial composition was predominantly African American, accounting for over 80 % of the population, with the remainder primarily non‑Hispanic White and small percentages of other groups. The city has experienced significant out‑migration, resulting in a high vacancy rate for housing.
Economy
The local economy has historically relied on river trade, rail transport, and manufacturing. In recent decades, economic activity has diminished, and the city faces challenges related to unemployment, poverty, and infrastructure degradation. Efforts have been made to revitalize the downtown area and promote heritage tourism focused on the city's Civil War history and historic architecture.
Infrastructure and Transportation
Cairo is intersected by Interstate 57 and U.S. Routes 51 and 60, providing road connections to larger regional centers. The city is also serviced by a municipal airport and retains freight rail lines, though passenger rail service is no longer active. Flood control measures, including levees, have been installed to mitigate the impact of periodic river flooding.

Cairo faces ongoing issues related to economic revitalization, population loss, and flood risk. Various state and federal programs have been pursued to address infrastructure repair, public safety, and community development, but progress has been incremental.
