Gilbert Nicolas, OFM (c. 1462 – 27 August 1532), religious name Gabriel-Maria, was a French Roman Catholic priest and a professed member of the Order of Friars Minor.

The former Queen consort was annulled from King Louis XII and went with Nicolas to Bourges to found a religious order.

[2] He travelled to Rome where he met with Pope Alexander VI to receive papal approval for the new congregation – though the College of Cardinals voiced their disapproval.

[2] Nicolas also provided advice and support for the reform of the Poor Clares and around 1520 visited the congregation's provinces in Ireland and Scotland in addition to the new Anglican England.

He also preached for a crusade against the Ottoman Empire and amongst his fellow Franciscans initiated research on the influence and reach of Lutheranism.
