Interstate 190 (I-190, locally known as One-Ninety) is a north–south auxiliary Interstate Highway in the United States that connects I-90 in Buffalo, New York, with the Canada–United States border at Lewiston, New York, near Niagara Falls. Officially, I-190 from I-90 north to New York State Route 384 (NY 384) is named the Niagara Thruway and is part of the New York State Thruway system. The remainder, from NY 384 to Lewiston, is known as the Niagara Expressway and is maintained by the New York State Department of Transportation (NYSDOT).

The freeway bisects downtown Buffalo before crossing Grand Island and travelling around the outskirts of Niagara Falls before crossing the Niagara River on the Lewiston–Queenston Bridge into the Canadian province of Ontario. In Canada, the freeway continues as Ontario Highway 405, a short spur connecting with the Queen Elizabeth Way (QEW), which in turn provides a freeway connection to Toronto, Canada's largest city. The 28.34-mile-long (45.61 km) route also provides access to the QEW at the Peace Bridge between Buffalo and Fort Erie, Ontario. I-190 is currently the only three-digit interstate to connect directly with Canada, and one of only two to connect to an international border, the other being I-110 in Texas, which connects to Mexico.

Parts of the highway were built along the former right-of-ways of the Lehigh Valley Railroad and the Erie Canal. The entire route was built as part of the New York State Thruway in the late 1950s and early 1960s and was completed in 1964. The cost of I-190's construction had been paid off by 1996, and, by law, the tolls along the freeway were supposed to be removed at that point; however, this did not occur until 2006.
