Catherine Hill Bay is a coastal bay and village
on the southern peninsula forming Lake
Macquarie, south of the Pacific Ocean entrance
channel at Swansea in New South Wales,
Australia. It is part of the City of Lake Macquarie
local government area. The village is the oldest
continuous settlement in the City of Lake
Macquarie.

A surf club is sited overlooking the beach at
Catherine Hill Bay, that is quite popular for
recreation.

The Catherine Hill Bay settlement was first
made after land was purchased on 1 April 1865.
The town of Cowper was created, to serve as a
base for coal mining by the New Wallsend
Company in 1873 with the first shipment on 17
December of that year. The name Catherine
Hill was adopted to commemorate the
schooner Catherine Hill that had run aground
in 1867
