Garden Island is an inner-city locality of Sydney, Australia, and the location of a major Royal Australian Navy (RAN) base. It is located to the north-east of the Sydney central business district and juts out into Port Jackson, immediately to the north of the suburb of Potts Point. Used for government and naval purposes since the earliest days of the colony of Sydney it was originally a completely detached island. It was joined to the Potts Point shoreline by major land reclamation work during World War II.

Garden Island today forms a major part of the RAN's Fleet Base East. It includes active dockyards (including the Captain Cook Graving Dock), naval wharves and a naval heritage and museum precinct. Approximately half of the major fleet units of the RAN use the wharves as their home port.

The northern tip of Garden Island is open to the public and contains the Royal Australian Navy Heritage Centre museum and an outdoor heritage precinct. Immediately south and above Garden Island on the Potts Point ridgeline is HMAS Kuttabul, the RAN's major administrative, training and logistics support establishment for the Sydney area. Although HMAS Kuttabul is administratively a separate facility to Garden Island, the two names are often referred to interchangeably.

Garden Island was originally an island in Sydney Harbour, but extension of the base and the construction of a dry dock in the channel between the island and the mainland have resulted in its connection to the mainland shore at Potts Point from the 1940s. The wharves of the naval base now stretch the length of the eastern side of Woolloomooloo Bay, from the suburb of Woolloomooloo to the end of the original island.

Garden Island is so-called because it was planted in 1788, in the first months of European settlement in Australia, to serve as a kitchen-garden by officers and crew of the First Fleet vessel HMS Sirius. Initials carved into a sandstone rock on the site are believed to be the oldest colonial graffiti in Australia, comprising the letters "FM 1788," representing Frederick Meredith who served as Sirius' steward. On 7 September 1811, ownership of Garden Island was declared to have transferred to the Governor's estate with produce dedicated for the exclusive use of Government House. The transfer had practical effect but due to an administrative error it was not formally registered, leaving the land in the legal ownership of the Navy, which successfully sought its return in 1866.
