Pickawillany was a Miami Indian village located on the current site of the city of Piqua, Ohio, in the United States.
It was created in 1748 by La Demoiselle, a Miami chief, and was destroyed by the French and their Indian allies under Charles Langlade in June 1752. (Langlade would also take part in Braddock's Defeat, three years later.)
The remains of Pickawillany may have been the site of a 1763 battle, described by Black Hoof, in which Miami and Wyandot fortified themselves against Delaware and Shawnee, who gave up the siege after seven days.
Chief Little Turtle, at Greeneville, is quoted as saying 'You discovered on the Great Miami traces of an old fort. It was not a French fort, brother, it was a fort built by me.' It is likely that this is an error in translation, and that he actually said "a fort built by Mishikinakwa (The Turtle)" which was also the name of an early Miami leader known to be at Pickawillany. Pickawillany was a trading post/fort.
