Waterloo was originally known as Prairie Rapids Crossing. The town was established near two Meskwaki American tribal seasonal camps alongside the Cedar River. It was first settled in 1845 when George and Mary Melrose Hanna and their children arrived on the east bank of the Red Cedar River (now just called the Cedar River). They were followed by the Virden and Mullan families in 1846. Evidence of these earliest families can still be found in the street names Hanna Blvd., Mullan Avenue and Virden Creek.

On December 8, 1845 the Iowa State Register and Waterloo Herald was the first newspaper published in Waterloo.

The name "Waterloo" supplanted the original name, "Prairie Rapids Crossing," shortly after Charles Mullan petitioned for a post office in the town. Since the signed petition did not include the name of the proposed post office location, Mullan was charged with selecting the name when he submitted the petition. Tradition has it that as he flipped through a list of other post offices in the United States, he came upon the name "Waterloo." The name struck his fancy, and on December 29, 1851, a post office was established under that name. The town was later called the same, and Mullan served as the first postmaster from December 29, 1851 until August 11, 1854. There were two extended periods of rapid growth over the next 115 years. From 1895 to 1915, the population increased from 8,490 to 33,097, a 290% increase. From 1925 to 1960, population increased from 36,771 to 71,755. The 1895 to 1915 period was a time of the rapid growth in manufacturing, rail transportation and wholesale operations. During this period the Waterloo Gasoline Traction Engine Company moved to Waterloo and shortly after, the Rath Packing Company moved from Dubuque. Another major employer throughout the first two-thirds of the 20th century was the Illinois Central Railroad. Among the others was the less-successful brass era automobile manufacturer, the Maytag-Mason Motor Company.
