Michael Crawford Kerr (March 15, 1827 – August 19, 1876) was an American lawyer and legislator who served as the first Democratic speaker of the United States House of Representatives after the Civil War.

He was elected to Congress in 1864 as a War Democrat, having vigorously opposed the Copperhead element in his district.

He won the praise of Republican Governor Oliver P. Morton for helping suppress illegal conspiracies by Copperheads.

In 1874, however, after a sharp contest he won the seat back, and on his re-entry into Congress was elected to the speakership.

He presided as Speaker at only the first session of the Forty-fourth Congress and died of consumption shortly after its adjournment.
