Pishobury or Pishiobury was the second great estate in medieval Sawbridgeworth, Hertfordshire.

This sub-manor of Pishobury originated in a grant of 74 libartes of land within the Manor of Sawbridgeworth, which Geoffrey de Mandeville, 1st Earlof Essex, who died in 1144, made to Warin FitzGerold (died 1216) and Henry FitzGerold (died after 1217) to hold by service of one Knight for each 20libartes. Henry survived his brother, but his niece Margaret FitzGerold/FitzWarin inherited Pishobury. She had married in 1200 Baldwin de Redvers,6th Earl of Devon, and in 1228 she levied a fine with William de Saye by which it was agreed that William and his heirs were to have free warren, ahunting right, throughout Sawbridgeworth.

The successive Lords of the manor of Pishobury had local hunting rights and their own park, too. In 1248 William de Say granted the heiress ofPishobury, Margaret FitzGerold/FitzeWarin, wife of Baldwin de Redvers, the right of free hunting on her own estate with dogs, birds or nets, andfree fishing in the river where it joined her lands; in return she recognized the de Says' right to have free warren over the whole Sawbridgeworth,including Pishobury. This right still exists today.
