Mosman Bay is a bay of Sydney Harbour adjacent to the suburb of Mosman, 4 km north-east of the Sydney CBD in New South Wales, Australia. Three ferry wharves are within the bay, all being served by the F6 Mosman Bay ferry service.

History

Originally known as Great Sirius Cove, this name lives on in the next bay to the east, Sirius Cove (originally Little Sirius Cove).

The bay was originally so named after Governor Arthur Phillip's flagship and only defence of the colony, {{HMS|Sirius|1786|6}}, which was refitted in the Bay in 1789, the second year of the colony's existence.{{cite book |last1=Andrews |first1=Graeme |title=A Pictorial History of Ferries: Sydney and Surrounding Waterways |date=1982 |publisher=AH & AW Reed Pty Ltd |location=Sydney |isbn=0589503863 |page=37 }}

In 1831, the bay's current namesake, Archibald Mosman, obtained a land grant for the area surrounding the bay. Together with his twin brother George, Mosman founded a whaling station within Mosman Bay.The Book of Sydney Suburbs, Compiled by Frances Pollen, Angus & Robertson Publishers, 1990, Published in Australia {{ISBN|0-207-14495-8}}, page 181 Substantial buildings and stone quaywork were erected. The quaywork remains (incorporated into later seawalls) as does the Old Barn, a sandstone building now used as a Scout hall.{{cite book |last1=Andrews |first1=Graeme |title=A Pictorial History of Ferries: Sydney and Surrounding Waterways |date=1982 |publisher=AH & AW Reed Pty Ltd |location=Sydney |isbn=0589503863 |page=38 }}

Charles Rosman's boatshed was located in the bay adjacent Mosman Wharf. Rosman hire boats, moorings and slipping services. He also ran several small ferries. Rosman Ferries are now run out of Berry's Bay. Other waterside establishments include the Sydney Amateur Sailing Club, 3rd Mosman Bay Sea Scouts, and the Mosman Rowers.

Around 1880, resident Captain Blix built a timber pile footbridge across the Bat in the vicinity of "the Barn". This was a more substantial replacement for a number of basic crossings created to avoid the long walk around the mud flats in the upper reaches of the Bay. This structure was demolished around 1900 to facilitate the reclamation of the mud flats and the creation of Reid Park. A 1901-built structure had a moveable central span to allow dredges to pass. The deteriorating bridge was closed in 1967.Plaque on site by Mosman Historical Society

A sewage aqueduct over Reid Park at the head of Mosman Bay was in 1904 as part of the Neutral Bay and Mosman branch sewerage scheme. The arched steel structure also supports a pedestrian way linking Avenue Road and Park Avenue Mosman.
