Dina Bélanger (30 April 1897 – 4 September 1929), also known by her religious name Marie of Saint Cecilia of Rome, was a Canadian professed religious and a professed member from the Religieuses de Jésus-Marie.
Bélanger was a noted musician and learnt the piano from her late childhood while teaching this later in her life though a period of ill health ceased this; successive bouts of poor health never hindered her spiritual or musical aspirations though weakened her due to contracting tuberculosis.
Her biographical account - spanning from 1924 until just a couple of months prior to her death - details her spiritual encounters with Jesus Christ in a series of visions.Bélanger's beatification was celebrated on 20 March 1993.
