Toetoes Bay is the easternmost of three large bays lying on the Foveaux Strait coast of Southland, New Zealand, the others being Te Waewae Bay and Oreti Beach. The 240 km Mataura River drains to sea at Toetoes Bay, first passing through the Toetoes Harbour estuary. Thirty kilometres (20 miles) in length, the bay is the southern end of the Awarua Plain, an area of swampy land stretching inland for about fifteen kilometres (10 miles). The eastern end of the bay is close to Slope Point, the South Island's southernmost point, and the western end of the Catlins.
