The Chicago, Burlington and Quincy Railroad (reporting mark CBQ) was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington or as the Q, the Burlington Route served a large area, including extensive trackage in the states of Colorado, Illinois, Iowa, Kansas, Kentucky, Missouri, Montana, Nebraska, Wisconsin, Wyoming, and also in New Mexico and Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad. Its primary connections included Chicago, Minneapolis-St. Paul, St. Louis, Kansas City and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the Zephyrs", and "The Way West". It merged into Burlington Northern in 1970.

In 1967, it reported 19,565 million net ton-miles of revenue freight and 723 million passenger miles; corresponding totals for C&S were 1,100 and 10 and for FW&D were 1,466 and 13. At the end of the year CB&Q operated 8,538 route-miles, C&S operated 708 and FW&D operated 1362. (These totals may or may not include the former Burlington-Rock Island Railroad.)

The earliest predecessor of the Chicago, Burlington and Quincy, the Aurora Branch Railroad, was chartered by act of the Illinois General Assembly on October 2, 1848. The charter was obtained by citizens of Aurora and Batavia, Illinois, who were concerned that the Galena and Chicago Union Railroad would bypass their towns in favor of West Chicago on its route; at the time, that was the only line running west from Chicago. The Aurora Branch was built from Aurora, through Batavia, to Turner Junction in what is now West Chicago. The line was built with old strap rail and minimal, if any, grading. Using a leased locomotive and cars, the Aurora Branch ran passenger and freight trains from Aurora to Chicago via its own line from Aurora to Turner Junction and one of the G&CU's two tracks east from there to Chicago. The G&CU required the Aurora Branch to turn over 70 percent of their revenue per ton-mile handled on that railroad; as a result, in the mid-1850s, surveys were ordered to determine the best route for a railroad line to Chicago.
