Eben Wever Martin (April 12, 1855 – May 22, 1932) was an American attorney and politician in South Dakota. A Republican, he was most notable for his service as a member of the United States House of Representatives during the early 20th Century.
In 1900, Martin was elected as a Republican to Seat B, one of South Dakota's two at-large seats in the United States House of Representatives. He was reelected in 1902 and 1904, and served from March 4, 1901, to March 3, 1907. He ran unsuccessfully for the United States Senate in 1906.
After the death of William H. Parker, Martin won a special election to fill the Seat B vacancy in the U.S. House, and was re-elected to three more terms, serving from November 3, 1908, to March 3, 1915. As a result of the 1910 United States census, South Dakota was apportioned three House members and created three districts. In Martin's 1912 reelection he ran successfully for South Dakota's 3rd congressional district seat. He was not a candidate for re-election in 1914.
