Nicholas Fitzherbert (1550 – 6 November 1612) was an English recusant gentleman who served as secretary to Cardinal William Allen and was found guilty of treason due to his Catholicism. He was the second son of John Fitzherbert of Padley, Derbyshire. Fitzherbert was the grandson of the judge Sir Anthony Fitzherbert (1470–1538), and first cousin to the Jesuit Thomas Fitzherbert.
