James William Keenan (February 10, 1856 – September 21, 1926) was an American professional baseball catcher.

He played most of his major league career with the Cincinnati Red Stockings of the American Association and later National League, after they became the Cincinnati Reds.

Keenan made his debut at age 17 with the New Haven Elm Citys of the National Association, but did not establish himself in the majors until 1884, when he became the regular catcher for the Indianapolis Hoosiers.

Before he played a game for Detroit, however, Keenan jumped to the Red Stockings, where he split time at catcher with Pop Snyder.

Over the next four seasons, he would split catching duties for the Red Stockings with Kid Baldwin.
