John Brant or Ahyonwaeghs (September 27, 1794 – August 27, 1832) was a Mohawk chief and government official in Upper Canada.

In the War of 1812, Brant and John Norton led native warriors to stop an American attack at the Battle of Queenston Heights in October 1812.

He helped his uncle try to get a formal deed for grant of land along the Grand River called the Haldimand Proclamation to the Six Nations.

In 1821, he went to England with Robert Johnson Kerr after Lieutenant-Governor Sir Peregrine Maitland informed them that they had no title to the northern part of the grant.

But a year later, his right to hold the seat was questioned as he did not own the amount of property required under the law at the time to sit in the Assembly, and he was thrown out of office.
