State Route 188 (SR 188) is a 22.2adj=midNaNadj=mid north–south state highway in West Tennessee, connecting the towns of Maury City and Alamo with Yorkville via Crockett Mills and Eaton.
SR 188 begins in Crockett County at an intersection with SR 54 and SR 88, approximately halfway between the towns of Maury City and Alamo.
