Daniel Featley, also called Fairclough and sometimes called Richard Fairclough/Featley (15 March 1582 – 17 April 1645), was an English theologian and controversialist.
A leading Calvinist disputant of the 1620s, he fell into difficulties with Parliament due to his loyalty to Charles I in the 1640s, and he was harshly treated and imprisoned at the end of his life.
