Tien Tsin Lookout is on a hill in the abandoned town of Cossack in Western Australia.
The town was first called Tien Tsin Harbour, named after the basque Tien Tsin that landed the first cattle stock into the area. Other names in the area came from the same ship. Butcher’s Inlet is named after Chief Officer Butcher who served under Captain Jarman, of whom Jarman Island had been named after.
The lookout gives a great view of the Cossack Township, in particular, the Pearl Street section where most of the remaining buildings are, along with the land backed wharf of Cossack’s port. The school can be seen in the opposite direction to the south-west.
To the north, Settler’s Beach can be seen, so a good overview of the whole area is seen from Tien Tsin Lookout.
The hill the lookout is on has a large water tank at the top. There are some paintings on the side of the tank.
Tien Tsin Lookout is on the Emma Withnell Heritage Trail 
, created as an Australian Bicentennial project.
