The Thousand Islands Parkway or TIP is a parkway in the Canadian province of Ontario, which extends easterly from an interchange with Highway 401 in Gananoque for approximately 40 kilometres (25 mi) to the community of Butternut Bay, in Elizabethtown-Kitley, west of Brockville. Evidence of its former use can be seen today in the wide right-of-way; the unused westbound lanes now serve as a bicycle trail and twin bridges span two locations along the parkway.
