Nicholas Skeres (March 1563 – c.1601) was a con-man and government informant.
Skeres worked as a servant for Thomas Walsingham. He was a government provocateur and a part of discovering the Babington Plot, working as a spy with Francis Walsingham. Skeres was involved in cases of fraud throughout his life, once working with Ingram Frizer. He was sentenced to Bridewell Prison for all of the crimes that he had committed. On May 30, 1593, Skeres and Robert Poley witnessed Ingram Frizer stab Christopher Marlowe at Eleanor Bull’s House over a dispute on the bill.
