Alngindabu, also spelt Alyandabu and also known as Lucy McGinness, (c.1874 – 23 September 1961), was a female senior elder (Almiyuk) from Chapana, near the Finniss River in the Northern Territory of Australia.

[1] After Stephen was dismissed from his job, the family left for Bynoe Harbour to find work, but along the way, Lucy's brother Maranda discovered tin ore.

Alngindabu used an old sewing machine to clothes for her family from calico flour sacks, and sang Irish[a] folk songs, learnt from her husband, to her children.

[1] Stephen died in 1918, and Alngindabu was taken with her two youngest children by the Aboriginal Protection Authority to live in the Kahlin Compound in Darwin,[1] making her one of the Stolen Generations.

[1] It is unclear when Alngindabu left Kahlin Compound but during World War II she was living in Katherine, Northern Territory and was evacuated from there to Balaklava, South Australia where she remained until 1946.

[4] Alngindabu was described by Ted Egan as "around six feet tall (183 cm), straight as a gun barrel, black, proud, barefooted, wearing a simple cotton frock and a wide-brimmed stockman's hat.
