The Nomoi Islands, also known as Mortlock Islands, are a group of three large atolls in the state of Chuuk, Federated States of Micronesia. They are located about 250 kilometres (160 miles) to the southeast of Chuuk. Satawan, the southern atoll, is the largest. Both Etal, the northern one, and Lukunor in the northeast are much smaller. They are located between 6 and 9 kilometres (3.7 and 5.6 miles) from each other.
