Easter Island (also known as Rapa Nui) is an island in the South Pacific Ocean of Earth. It was originally inhabited by the Polynesian people, who gave it the name, "The Navel of the World". The island was most famed for the rows of large head sculptures facing out across the ocean. It was the location of Rano Raraku, an inactive volcano.
The island's culture had become stagnant, evidenced by the enormous effort expended to repeatedly build the same statues. In 2268, Spock considered the cultural circumstances comparable to those in a city discovered on a planet 3,000 light years from the galactic core which consistently reused the same architectural forms.

Zak Kebron, the stoic Brikar security and tactical officer of USS Excalibur in 2373, was more than once described as being as immobile as an Easter Island statue. During a security assignment in 2361, he once hid within a statue for three days. (NF novel: Martyr, NF - No Limits short story: "Waiting for G'Doh, or, How I Learned to Stop Moving and Hate People")
