U Thant Island

Island Small Manhattan island and memorial named for U Thant

U Thant Island is a small East River islet near Manhattan, named for the former UN secretary; visible from boats and waterfront walks, it draws attention for its gazebo, bird colonies and city‑river views.

U Thant Island is a small triangular islet in the East River, situated just off the southern tip of Roosevelt Island in New York City. It is an uninhabited, tree-covered islet informally named in honour of U Thant, the third Secretary-General of the United Nations.

The islet is best known as a quiet green spot visible from Roosevelt Island and the Manhattan and Queens shorelines; it has no public facilities and no official park infrastructure. Access is by private boat only and the site is managed informally rather than as a public park.

The name reflects local dedication to U Thant and the islet functions as a visual landmark on the East River rather than a developed visitor attraction.

U Thant Island lies in the East River adjacent to the southern end of Roosevelt Island between Manhattan and Queens, visible from the island’s southern promenade and nearby bridges.

Access: No public bridges or regular ferry service connect to the islet; access is by private boat only.
Local dedication: Known locally by its dedication to U Thant, the small triangular islet contains a modest planted area and an informal memorial used by visitors and local groups.
