Junius Kaʻae was a Native Hawaiian politician of the Kingdom of Hawaii. In 1887, he was implicated in the infamous bribery scandal involving King Kalākaua over the sale of an opium license to Tong Kee.

Kalākaua, sometimes called The Merrie Monarch, was the last king and penultimate monarch of the Kingdom of Hawaiʻi, reigning from February 12, 1874, until his death in 1891. Succeeding Lunalilo, he was elected to the vacant throne of Hawaiʻi against Queen Emma. Kalākaua had a convivial personality and enjoyed entertaining guests with his singing and ukulele playing. At his coronation and his birthday jubilee, the hula, which had hitherto been banned in public in the kingdom, became a celebration of Hawaiian culture.
