Tinley Park is a village located in Cook County, Illinois, United States, with a small portion in Will County. The population was 56,703 at the 2010 census. It is one of the fastest growing suburbs southwest of Chicago. In 2009, Tinley Park was selected by BusinessWeek as the best place to raise a family in America. In 2017, Tinley Park was listed as one of the 50 safest cities in America.
Settlement of the area which now comprises Tinley Park began in the 1820s by emigrants from the Eastern United States. German settlers became predominant in area by the 1840s, and the village was originally established in 1853 as "Bremen". Irish, English, Scottish, Canadian, and other American settlers were also common in the area.
In the late 19th century, railroads expanded rapidly, and the village happened to be located on the Chicago, Rock Island and Pacific Railroad line. The influence of the railroad on Bremen was so great that, in 1890, its name was changed to Tinley Park in honor of the village's first railroad station agent, Samuel Tinley, Sr. Even the village's official incorporation took place at the train depot on June 27, 1892.
With the railroad came industry and commerce.
