Donal Cam O'Sullivan Beare, Prince of Beare, 1st Count of Berehaven (Irish: Domhnall Cam Ó Súileabháin Bhéara; 1560 – 16 July 1618) was an Irish nobleman and soldier who was the last independent Chief of the Name of Clan O'Sullivan. He was thus the last O'Sullivan Beare, a title of the Gaelic nobility of Ireland, and Lord of the Beara Peninsula in the southwest of Ireland during the early seventeenth century, when the English Crown was attempting to secure their rule over the whole island.
