Daniel Russell Brown (March 28, 1848 – February 28, 1919) was an American politician and the 43rd Governor of Rhode Island.

D. Russell Brown was born in Bolton, Connecticut, United States, on March 28, 1848.

He won the first election by popular vote, was then reelected by the General Assembly the next year, when no candidate reached the required majority, and won the popular vote again in his third gubernatorial election.

In his last term, he played a key role in the adoption of a constitutional amendment that permitted election by a plurality rather than a majority vote.

He was suggested as vice presidential candidate at the Republican National Convention of 1896, having the support of New England, but was not selected.
