Maureen Paula O'Sullivan (17 May 1911 – 23 June 1998) was an Irish actress best known for playing Jane in the Tarzan series of films starring Johnny Weissmuller.
O'Sullivan was born in Boyle, County Roscommon, Ireland, in 1911, the daughter of Mary Eva Lovatt (née Frazer) and Charles Joseph O'Sullivan, an officer in the Connaught Rangers who served in World War I. Maureen returned to Boyle in 1988 to be honoured by the town. She attended a convent school in Dublin, then the Convent of the Sacred Heart at Roehampton (now Woldingham School), England. One of her classmates there was Vivian Mary Hartley, future Academy Award-winning actress Vivien Leigh. After attending finishing school in France, O'Sullivan returned to Dublin to work with the poor. In October 1929, she sailed to New York with her mother on the British steamer R.M.S. Baltic, on the way to Hollywood to work for the Fox Film Corporation.
