The Episcopal Diocese of Hawai'i is the ecclesiastical territory or diocese of the Episcopal Church of the Anglican Communion in the United States encompassing the state of Hawaii. It is led by the Episcopal Bishop of Hawaii pastoring the Hawaiian Islands from the Cathedral Church of Saint Andrew in Honolulu.

The territorial jurisdiction which the Episcopal Diocese of Honolulu holds today was given up to American Episcopalians after the 1893 overthrow of Queen Liliuokalani, head of the Church of Hawaii. The Church of Hawaii, also called the Hawaii Reformed Catholic Church, was established by King Kamehameha IV and his consort Queen Emma in 1862. The king and queen, friends of Queen Victoria of the United Kingdom, were devout members of the Church of England. Episcopalians continue the Anglican Church of Hawaii tradition of celebrating the Feast of the Holy Sovereigns each November 28, in honor of Kamhehameha IV and Queen Emma.
