Perched on a bluff above the Des Plaines River Valley about 40 minutes southwest of Chicago, Lemont is a close-knit village where deep-rooted heritage and natural surroundings shape everyday life. Its name comes from the French phrase meaning "the mountain," a nod to the elevated terrain that gives the community its distinctive character. Limestone quarrying built this town, and the historic downtown still reflects that legacy through stone architecture along Main and Stephen streets. Today, Argonne National Laboratory anchors the area's research and employment landscape, while Lewis University and Moraine Valley Community College are both within a short drive. The Hindu Temple of Greater Chicago, one of the largest of its kind in the country, also calls Lemont home, reflecting the range of cultural influences that have taken root here over generations. The rental market offers a mix of townhomes, single-family rentals, and apartment communities, with rents that consistently track below the Illinois state average. Lemont spans just 10 square miles across parts of Cook, DuPage, and Will counties, so getting around is straightforward, and the Lemont Metra Station on the Heritage Corridor line provides a direct connection to downtown Chicago for commuters who prefer the train.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
