Mother Geraldine Scholastica Gibbons (c. 1817 – 15 October 1901) was an Irish-Australian nun, founder and first superior of the Sisters of the Good Samaritan.

The Archbishop Bede Polding of Sydney was keen to grow the congregation in his archdiocese, waiving the dowries that Gibbons' father was unable to pay on their behalf.

This sparked tension in the congregation, with De Lacy resigning from her position as rectress of St Vincent's Hospital, Sydney in 1859, claiming pressure for the convent rule to move from Vincentian to a modified Benedictine from the archiepiscopal hierarchy.

On 2 February 1857 he requested that Gibbons become superior of a new order that would amalgamate her congregation and a new group of women who had formed the Community of the Good Shepherd.

Gibbons remained superior of the new congregation until 6 September 1876, when she returned to the Sisters of Charity, working with the poor in the Hobart convent.
