Marie Henrietta Louise Outhwaite (née Roget) (1811 – 4 July 1905) was a French-born New Zealand settler.
She was a leading figure in the Catholic church in Auckland and a close friend and supporter of Suzanne Aubert.
[1] Outhwaite's husband became the first registrar of the Supreme Court in New Zealand, and the couple became involved in social and philanthropic works in Auckland.
Outhwaite became acquainted with Suzanne Aubert and her Catholic order of nuns, and supported her work.
In 1871 Aubert stayed with the Outhwaites for six weeks when she had to move out of her cottage at Shelly Bay.
