The BNSF Line is a Metra commuter rail line operated by the BNSF Railway in Chicago, Illinois and its western suburbs, running from Chicago Union Station to Aurora, Illinois through the Chicago Subdivision. In 2010, the BNSF Line continued to have the highest weekday ridership (average 64,600) of the 11 Metra lines. While Metra does not refer to its lines by particular colors, the BNSF line's color on Metra timetables is "Cascade Green," in honor of the Burlington Northern Railroad.

As of September 8, 2025, the public timetable shows 97 trains (47 inbound, 50 outbound) on the BNSF Line on weekdays. Of these, 32 inbound trains originate from Aurora, two from Lisle, one from Downers Grove Main Street, 10 from Fairview Avenue, and two from Brookfield. Five outbound trains terminate at Brookfield, seven at Fairview Avenue, three at Naperville, and the rest at Aurora. Weekend and holiday service consists of 40 trains (20 in each direction), with all trains traveling between Union Station and Aurora.

The line is operated by BNSF under a "purchase of service agreement" with Metra, inherited from Burlington Northern. While Metra owns all rolling stock, the management and crews are BNSF employees. BNSF is the owner of the right-of-way, controls the line and handles dispatching from corporate headquarters in Fort Worth, Texas. Metra imposes a 70 mph maximum allowed speed for passenger trains. The BNSF Line is the only remaining Metra commuter line that operates via a purchase-of-service agreement since the Union Pacific Railroad transferred the operations and supplying of commuter trains to Metra for the routes originating from the Ogilvie Transportation Center in 2025.
