U.S. Highway 161 (US 161) was a U.S. Highway in Iowa that ran from Keokuk to Dubuque by way of Cedar Rapids. It was designated in 1925 and signed in 1926 along two primary highways. The route began at the Mississippi River with US 61 southwest of Keokuk ran north through Mount Pleasant and Iowa City to Cedar Rapids. There, it turned to the northeast through Anamosa and Monticello towards Dubuque. The route ended at US 61 in Key West, a few miles west of Dubuque.
The route changed very little while it was in service. It was paved from end to end by the summer of 1932. In January 1938, it was removed from the US Highway System. From Keokuk to Cedar Rapids, it was replaced by US 218, which was extended southward. From Cedar Rapids to Key West it was replaced by US 151, which was extended westward.
