John Joseph LaFalce (born October 6, 1939) is an American politician who served as a Congressman from the state of New York from 1975 to 2003.

From 1965 to 1967, LaFalce served in the United States Army during the Vietnam era, leaving active duty with the rank of captain.

In 1974, at the age of 35, LaFalce became the second Democrat, and the first since 1912, to win election to what was then the 36th congressional district of New York, which was based in Niagara Falls and also included much of northern Buffalo and the western suburbs of Rochester.

LaFalce played a key role in airing the grievances of the displaced residents of Love Canal, which was part of his district, and spearheading the federal government's subsequent response to the environmental disaster.

LaFalce also played a key leadership role in introducing and championing what ultimately became the Sarbanes-Oxley Act, signed by President Bush in July 2002.

One plan called for the merger of LaFalce's territory with the neighboring 27th district of Republican Jack Quinn, a longtime friend who represented the other portion of Buffalo.
