The Piankeshaw, Piankashaw or Pianguichia were members of the Miami tribe who lived apart from the rest of the Miami nation, therefore they were known as Peeyankihšiaki ("splitting off" from the others, Sing.: Peeyankihšia - "Piankeshaw Person"). When European settlers arrived in the region in the 1600s, the Piankeshaw lived in an area along the south central Wabash River that now includes western Indiana and Illinois. Their territory was to the north of Kickapoo (around Vincennes) and the south of the Wea (centered on Ouiatenon). They were closely allied with the Wea, another group of Miamis. The Piankashaw were living along the Vermilion River in 1743.
