Kamāmalu Kalani-Kuaʻana-o-Kamehamalu-Kekūāiwa-o-kalani-Kealiʻi-Hoʻopili-a-Walu (1802–1824) was Queen consort of the Kingdom of Hawaiʻi as the wife of King Kamehameha II. Kamāmalu was short for Kamehamalu or Kamehamehamalu meaning "the Shade of the Lonely One", honoring her father, "the Lonely One". She is not to be confused with her niece, Princess Victoria Kamāmalu.

She was the eldest daughter of Queen Kalākua Kaheiheimālie and King Kamehameha I. She was referred to as Kekūāiwa for the early part of her life. According to John Papa ʻĪʻī, she was betrothed to her half-brother Kamehameha II from birth and they were married when she was twelve and he was seventeen or eighteen. Her younger sister Kīnaʻu later also became wife of Kamehameha II as did their half-sister Kekauluohi by their mothers Kalakua Kaheiheimalie. Even though her husband had four other wives (two of them her sisters and the two others her nieces), Kamāmalu was her husband's favorite wife.

In 1823, she joined a royal procession honoring her husband's accession to the throne in a car modeled as a whaleboat. It was fastened to a platform 30 feet (9.1 m) long by 12 feet (3.7 m) wide and borne by 70 men. The boat was lined and the whole platform covered with fine imported broadcloth and tapa cloth of rich colors. The only dress of the queen was a scarlet silk Paʻū, (a feather cloak), and a coronet of feathers. She was seated in the middle of the boat, and screened from the sun by an immense Chinese umbrella of scarlet damask, ornamented with gilding and tassels, supported by a chief standing behind her in a scarlet loincloth and feather helmet. On the boat stood Prime Minister Kalanimoku and national orator Naihe in feathered helmets and bearing a kahili or feather staff of state.
