Henry Rossiter Worthington (December 17, 1817—December 17, 1880) was an American mechanical engineer, inventor, industrialist and founder of the American Society of Mechanical Engineers in 1880.

Worthington had several inventions leading to the perfection of the direct steam pump (1845—55), patented the duplex steam pump (1859), and built the first duplex waterworks engine, widely adopted and used for more than 75 years. He established a pump manufacturing plant, New York City, in 1859.
