Blackburn Barrett Dovener (April 20, 1842 – May 9, 1914) was a Republican politician from West Virginia who served as a United States representative.

After studying law, he was admitted to the bar in 1873 and entered practice in Wheeling, West Virginia.

He gained some fame there as counsel to murder defendant Taylor Strauder, taking the case (Strauder v. West Virginia) all the way to the Supreme Court of the United States, winning an important legal victory for the civil rights of freedmen.

It was when he came to Wheeling to be mustered in that he first met Miss Lynch, then a beautiful young girl of seventeen.

His candidacy for renomination was unsuccessful, and he returned to his legal practice in Wheeling.
