John Owen Dominis (March 10, 1832 – August 27, 1891) was prince consort of the Kingdom of Hawaiʻi as the husband of Queen Liliʻuokalani from January 29, 1891, until his death that year.

[6] Working for Josiah Marshall of Boston, Massachusetts, Captain Dominis sailed from North America across the Pacific, often stopping in Hawaii.

In 1837 the captain moved his wife and son from New York to Honolulu, Hawaii, leaving their two daughters at boarding school where they died young.

King Kamehameha III awarded some land to the family in 1842 as settlement of a lawsuit with the British Consul Richard Charlton.

In 1846 he sailed for China on the Brig William Neilson, intending to purchase Chinese-made furniture for the house which was nearing completion.

[9]: 13 On September 16, 1862 Dominis married Lydia Kamakaʻeha Pākī, later Queen Liliʻuokalani, whom he had met during school days.

They had been engaged for two years, but had to delay their wedding due to the death of Prince Albert, the young son of King Kamehameha IV.

Liliʻuokalani became Queen when her brother King Kalākaua died on January 20, 1891, which made Dominis Prince Consort.
