William Francis Yardley (January 8, 1844 – May 20, 1924) was an American attorney, politician and civil rights advocate, operating primarily out of Knoxville, Tennessee, in the late 19th century. He was Tennessee's first African-American gubernatorial candidate, and is believed to have been the first African-American attorney to argue a case before the Tennessee Supreme Court. He published a newspaper, the Examiner, that promoted African-American rights, and was an advocate for labor and the poor both as an attorney and as a politician.
