Toyota Motor Manufacturing Indiana (TMMI) is an automobile manufacturing plant located in Gibson County, Indiana, United States, nearly halfway between Princeton and Fort Branch, and mostly in Union Township.

Toyota Motor Manufacturing Indiana was built in May 1996[2] to begin production of a full-size pickup truck solely for the North American market.

Toyota also announced that production of the Highlander would be shifted to TMMI and would start in 2009.

Both plants have joined weld, stamping, and plastic production sections.

TMMI is the sole source of Highlanders for all markets worldwide except China.
