Abigail Maheha (July 10, 1832–?) was a member of the royal family during the Kingdom of Hawaii.
Maheha was the daughter of High Chief Namaile and High Chiefess Kuini Liliha. Her mother was the royal governor of O'ahu during the regency of Queen Kaʻahumanu. She was descended from Kahekili II, Moi of Maui, and High Chief Hoapili.
She was adopted or hanaied by her aunt, Princess Anne Kekauonohi. Her hanai mother was a granddaughter of Kamehameha the Great who united the Hawaiian Islands into one kingdom and was also the youngest consort of the deceased Kamehameha II and served as Governor of Kauai.
She was among those chosen by King Kamehameha III eligible for throne of the Kingdom of Hawaii to attend the Chiefs' Children's School, also known as the Royal School of Hawaii. Her sister Jane Loeau also attended Royal School. She was taught by American missionaries Amos Starr Cooke and his wife Juliette Montague Cooke. During their Sunday procession to church it was customary for boys and girls to walk side by side; Abigail walked beside Alexander Liholiho, the future King Kamehameha IV.]
She left the school on January 18, 1847, married Keaupuni on February 3, 1847 but they divorced. She married Kiaaina Wahineaea on July 17, 1857 on the island of Kauaʻi. Her first name was spelled "Apigaila" on the marriage record.
