Gregory Blaxland (17 June 1788 — 31 December 1852) was a pioneer farmer and explorer.
In 1808 was associated with the Macarthur faction in the deposing of Governor Bligh.
In January 1827 Blaxland was elected by a public meeting with two others to present a petition to Governor Darling asking that "Trial by jury" and "Taxation by Representation" should be extended to the colony.
