Frank Cowan (December 11, 1844 – February 12, 1905) was an American lawyer, medical doctor, writer, and secretary to U.S. President Andrew Johnson. He was born in Greensburg, Pennsylvania to Lucetta Oliver and Edgar Cowan, a local lawyer. He studied at Jefferson College, but faculty there expelled him for a prank. In 1861, however, he moved to Washington, D.C.
