Robert Baker (April 1862 – June 15, 1943) was an American businessman and politician who served one term as a U.S. Representative from New York from 1903 to 1905.

Born at Bury St. Edmunds, Suffolk, England, U.K. in April 1862, Baker attended the common schools.

[2] In March 1902, he was appointed an auditor in the office of the New York City Comptroller, a position he reportedly received from Democratic Party leaders in exchange for withdrawing his candidacy for sheriff.

[6] In addition, he offered an unsuccessful resolution that would have condemned the "Bloody Sunday" massacre in St. Petersburg, Russia, in which the Tsar's imperial guard fired upon unarmed demonstrators who wanted to present a petition advocating for improved working conditions and higher wages.

[9] Later in life he reversed his pacifist philosophy, and became a strong proponent of war with Nazi Germany, writing poems and letters to the Brooklyn Eagle in support of the cause.
