Moku O Lo'e, or Coconut Island, is a 28-acre island in Kāne'ohe Bay off the island of Oahu in the state of Hawaii, United States. It is a marine research facility of the Hawaii Institute of Marine Biology of the University of Hawaii.

In the early 1930s, Moku O Lo'e was a privately owned by the heir to the Fleischmann yeast fortune. It was later converted to a rest and relaxation station for the U.S. Navy flyers during WW II.

In 1946 it was purchased by the Pauley family who used the island for summer get-aways and hosted many notable guests. From the mid-80s to mid-90s Japanese real estate investor Katsuhiro Kawaguchi owned the island and permitted the University of Hawaii to use some of its areas for research. In 1995, the Edwin Pauley Foundation granted a gift of $9.6 million to the University of Hawaii Foundation to purchase the private half of the island and build new laboratories on it.

The island is now completely owned by the state and is the facility for the Hawaii Institute of Marine Biology, part of the University of Hawaii. It is the only U.S. laboratory built on a coral reef.
