Frank Morey (July 11, 1840 – September 22, 1890) was an American planter, politician, and soldier in the Union Army (1861–1865), reaching the rank of colonel; afterward he moved to Louisiana, where he became a planter and sold insurance.

His election in 1876 was contested, and he lost his seat in June of that year to Democrat William B. Spencer.

He was appointed as a commissioner to revise the statutes and codes of the State under Reconstruction, to reflect national constitutional amendments granting freedmen citizenship and the right to vote.

He presented his credentials as a Member-elect to the Forty-fourth Congress as well, but it was contested by his Democratic opponent, William B. Spencer.

The Democrats also regained control of the Louisiana state legislature that year, in an election marked by violence as the White League worked to suppress black voting.
