Munro Island Nature Reserve is located in the Clarence River on the north coast of NSW near the township of Lawrence. The reserve, which includes all of Munro Island, is about 27 hectares in size. It is one of only four islands included in the protected area system out of the forty islands within the Clarence River system.

The reserve protects a diversity of habitats within a relatively small area, including mangroves and estuarine intertidal zones, as well as developing rainforest and swamp sclerophyll communities. These habitats support a high diversity of bird species, including songbirds, shorebirds and birds of prey. A number of migratory species have also been recorded using the feeding and roosting habitat available on the island, particularly the sandflats and intertidal zones.

No facilities are provided on this reserve.
