Webster Wagner (October 2, 1817 – January 13, 1882) was an American inventor, manufacturer and politician from New York.

He founded the Wagner Palace Car Company, located in Buffalo, New York.

Several legal battles with the Pullman Company failed to put him and his partners out of business; at the time of his death the two companies were completing a merger.

Wagner was killed in the 1882 Spuyten Duyvil train wreck while returning from Albany to New York City when two trains of the New York Central and Hudson River Railroad collided in between the Kingsbridge and Spuyten Duyvil stations in The Bronx, two weeks into his sixth Senate term, on January 13, 1882.

[2] Webster Wagner House at Palatine Bridge was added to the National Register of Historic Places in 1973.
