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 but was joined to the Potts Point shoreline by major land reclamation work during World War II.

Today, Garden Island 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.
