James Riskinner or Reiskimmer was a 17th-century English privateer who operated from Providence Island against Spanish shipping during the late 1630s. A lieutenant on the ship Warwick, then part of a fleet under the command of Nathaniel Butler, he later took part in a privateering expedition under Butler between May–September 1639. According to Nathanial Butler's journal, James's father, Captain Nicholas Reiskimmer, was appointed governor of Association Island (Tortuga), but died shortly after arriving there.
